Hermit crabs do not have their own shells and live in empty snail shells for protection. They hatch from eggs laid in the ocean and live there until they resemble adults. Hermit crabs have soft abdomens so they seek shelter in shells to avoid predators. They use one claw to seal themselves in the shell and the other to eat. Hermit crabs are crustaceans that molt their exoskeletons to grow, and they live in groups both in the ocean and on land.

Puntius ticto
The document discusses the ticto barb fish (Puntius ticto). It is found in shallow waters of lakes and rivers in parts of South Asia. It has silver and gold coloring with two black spots and grows up to 10 cm long. It eats small crustaceans, insects and plankton. In aquariums, ticto barbs are active schooling fish that spawn among gravel but may eat their own eggs, so separation is often needed after spawning. Conservation efforts could focus on culturing this species commercially given threats to wild populations.
Plankton and fisheries
Plankton are small organisms that drift or float in water bodies. They fall into two categories: phytoplankton, which are plant-like organisms, and zooplankton, which are animal-like. Plankton play an important role in the global carbon cycle and food web as they are both a primary producer through photosynthesis and a food source. Many fish rely on plankton as their sole or primary food source, and plankton blooms influence fisheries. The abundance of plankton can also indicate fish populations, as nutrient-rich areas attract both plankton and fish. Plankton and fish have a complex, interdependent relationship through food chains, gas exchange, and some plankton acting
Economic important fishes
This document contains information on several fish, crustacean, and mollusk species. It describes the taxonomy, physical characteristics, habitat/ecology, and economic importance of species including the rohu fish, catla fish, mrigal carp, pomfret fish, giant river prawn, crabs, and pearl oyster. The rohu, catla, and mrigal are important aquaculture species in South Asia and are commonly farmed together. The document also provides details on the taxonomy, morphology, and life cycle of these organisms.
Agnathan Fish Notes
The document discusses early fish evolution, including jawless fish like hagfish and lampreys. It describes key characteristics of hagfish, including that they have no backbone but are still considered vertebrates. It then discusses different classes of jawless fish like lampreys and ostracoderms, which were early armored fish. Placoderms followed as the first jawed fish.
Inland fishing craft and gears
Coracles are dominant fishing craft in South Indian reservoirs. They are made of a large, circular basket with low sides and a hide covering. Fishermen use gill nets, shore seines and longlines from coracles. Catamarans, made of 3-5 logs tied together, are used in pairs for boat seines and individually for longlines and cast nets. Common inland fishing gears include cast nets, gill nets, seines, lift nets, drag nets, hooks and lines, and traps. Trawlers have been tried experimentally in some Indian reservoirs.
Exocoetus
Flying fish have unusually large pectoral fins and streamlined bodies that allow them to glide through the air over water to escape predators. They live in tropical and subtropical oceans around the world. When threatened, they can propel themselves out of the water by rapidly flapping their tails and gliding with extended fins for distances up to 50 meters. Their ability to fly enables them to evade predators and return safely back to the sea.
Fish reproduction
The document summarizes different aspects of fish reproduction, including both asexual and sexual reproduction. It discusses types of hermaphroditism, modes of sexual reproduction such as oviparity and viviparity, clutch sizes, courtship behaviors, sexual dimorphism, and various strategies for protecting eggs and young, such as mouth brooding, external brooding, gill brooding, and nest building. Sexual maturity varies widely between species, from shortly after birth to over 10 years of age depending on size, lifespan, and other factors.

Great white sharks project
The great white shark, also known as white pointer or white death, has a scientific name of Carcharodon carcharias. It lives in coastal waters between 12 to 24 degrees Celsius around the world. Great whites have over 3,000 teeth, a keen sense of smell, and prey on fish, seals, sea lions, dolphins and small whales. Females mature at around 15 years old when they are 15 to 18 feet long. Though attacks on humans are rare, great whites are an apex predator capable of sensing prey from great distances and inflicting deadly wounds with their serrated teeth.
Fishing crafts
A fishing gear is the tool with which aquatic resources are captured, whereas the fishing method is how the gear is used. Gear also includes harvesting organisms.

Swim bladder general organization and circulation and function
The document summarizes the general organization, circulation, types, gas secreting complex, and functions of the swim bladder in fish. It notes that the swim bladder contains gas and develops from the gut wall. Blood supply comes directly from arteries or the coeliaco-mesenteric artery. Depending on connections to the esophagus, swim bladders are either physostomous or physoclistous types. The anterior part secretes gas while the posterior part absorbs gas. Main functions include respiration, sound production, hearing, pressure sensing, and providing buoyancy.
Marine Mammals
Marine mammals are warm-blooded and air-breathing, with hair or fur and mammary glands to feed live young. They are divided into three main categories: Carnivora like seals, sea lions, and walruses; Sirenia like manatees and dugongs; and Cetacea including whales, dolphins, and porpoises. Cetacea are further divided into toothed whales like dolphins and sperm whales, and baleen whales which filter feed using baleen plates. Marine mammals have various adaptations for living in the ocean like blubber for insulation and streamlined bodies for fast swimming.

Fish Pituitary Gland
The fish pituitary gland is located in the brain and has two parts - the glandular and nervous parts. It can be collected through dissection by removing part of the scalp or through the foramen magnum. The gland is then preserved in alcohol or acetone and stored. For injection, it is homogenized in water or saline, centrifuged, and the supernatant is used. Females receive two injections of the extract 6 hours apart at specific dosage levels based on the fish species.
Aquarium plant: Utility and propagation
Being at the base of food chain, plants are important in any ecosystem. Plants help to provide the biological balance, besides creating bio-topic aquarium.
The presence of different aquatic plant provides a number of houses to the fishes inside the aquarium.
Most fresh water aquariums can be set up with live plants and whenever possible, it is recommended to do so.
Introduction to Catla catla
1) Catla catla, commonly known as catla, is a freshwater fish found predominantly in Asia, including India, Bangladesh, and Nepal. It is a fast-growing, planktivorous carp that feeds on zooplankton and algae.
2) Catla has prominent lips and thick lower jaws without barbels. It grows rapidly, reaching lengths of over 1 meter. It breeds during the monsoon season.
3) Catla is farmed using nursery, rearing, and stocking ponds with lime, organic and inorganic fertilizers added to enhance food production. It is supplemented with feeds including rice bran, fishmeal, and aquatic insects.
Difference between shark and Teleost
Sharks and teleost fish differ in several key anatomical features. Sharks have cartilaginous skeletons, 5-7 gill slits not covered by an operculum, heterocercal caudal fins, and extract urea as their main nitrogenous waste product. In contrast, teleosts have bony skeletons, 7-8 gills covered by an operculum, homocercal caudal fins, and extract ammonia. Reproduction also differs between the two classes, with sharks exhibiting various forms of internal fertilization and viviparity/oviparity while most teleosts practice external fertilization through egg-laying.
Coldwater fisheries in India
This document discusses cold water fisheries in India. It describes the temperature range for cold water fisheries (5-25°C) and notes that states like Kashmir, Himachal Pradesh, and Uttarakhand are well-suited for cold water fisheries. It identifies important cold water fish species in India like various types of mahseer and trout. Mahseer can grow up to 1.5 meters long and breed from July to September. Trout generally feed on other fish and aquatic invertebrates. Cold water fisheries provide income, employment, and food for local populations and have significant potential to contribute to India's fisheries sector and economy.
Prawn fisheries
Prawn is a common name for small aquatic crustaceans with an exoskeleton and ten legs some of which can be eaten.

8 Fun Facts About Hermit Crabs
Trying to decide if you want a hermit crab as a pet? Read this slideshare to learn why these little critters are so fun and interesting!
Priyasha Rocky Shores
1. Hermit crabs do not have an exoskeleton and instead live inside empty snail and whelk shells for protection and shelter.
2. They are commonly found in rocky shores where there is ample food and empty shells.
3. Hermit crabs have many predators including seagulls, pelicans, octopuses, other crabs, humans, and seals.
Crabs by andres
Crabs live in rocky shores, shallow oceans, and around volcanic vents. They eat small ocean animals, starfish, sea turtles, and birds. When threatened, crabs can snap off a leg and regrow it to escape, while some swim using their legs like paddles or have flat bodies suited for hiding. The report also discusses crab anatomy, habitats, diet, and includes a poem about crabs.
Crabs
Crabs live in various habitats including deep holes, oceans, lakes and streams. They come in different colors like red, blue and black, and sizes from small to big. Crabs have claws called nippers and bigger crabs will eat smaller crabs if they are small enough. Crabs at Castle Point live under rocks along the rocky shore and can live up to 100 years if not killed by predators like humans.
Shellfish intro
The document discusses various types of shellfish, including their classification, quality standards, storage, and preparation methods. It describes how molluscs like mussels and scallops have hinged or spiral shells, while crustaceans like crab and lobster have armored exoskeletons. Live shellfish are preferable to ensure freshness. Proper storage in the refrigerator is important to prevent spoilage from bacteria. Cooking methods generally involve quick cooking to retain moisture and texture. Popular types of shellfish - lobster, crab, scallops, oysters - are highlighted.
Crabs and corals and water movement presentation
Crabs play an important role in helping corals survive in environments with slow water flow and high sedimentation. Dr. Stewart observed that coral colonies living in these conditions were often healthy if they had crabs residing within their branches. Through a series of field and lab experiments, Dr. Stewart found that crabs actively remove sediment from coral polyps. Corals with crabs had lower mortality and bleaching than those without crabs. This mutualistic relationship allows both organisms to thrive in otherwise challenging environments.
Mud crab
The document provides information about the mud crab (Scylla serrata), including its classification, distribution, ecology, and methods for farming and hatchery management. It notes that mud crabs are found naturally in the Indo-Pacific region and are an economically important species. Mud crab farming can be done using grow-out systems, where young crabs are raised for 5-6 months until market size, or fattening systems, where soft-shelled crabs are raised for a shorter period. Hatchery management involves broodstock selection and care, spawning and larval rearing techniques, and achieving survival rates as high as 18.1% compared to the world average of 3-3.5
Crab Power Point
Crabs are arthropods that have 10 legs, a hard shell, and walk sideways. There are almost 5,000 species of crabs, with 4,500 being true crabs and 500 being hermit crabs that steal shells from other animals for protection. The largest crab is the Japanese spider crab, with a leg span of up to 3.7 meters, while the largest land crab is the coconut crab with a leg span of up to 75 cm. Crabs are found on beaches around the world and come in various colors depending on the species.
Pointillism Painting Project
Georges-Pierre Seurat was a French Neo-Impressionist painter in the late 19th century who developed the technique of pointillism. Pointillism involved applying small dots or points of pure color close together so that from a distance they visually blend in the eye of the observer. Seurat was inspired by scientific theories on color and contrast, and used this technique to carefully organize color on his canvases. He would labor for up to a year on preparatory studies before beginning a final painting using the pointillist method.
Pointillism
Pointillism is a technique of painting where small dots of pure color are applied in patterns to form an image. When viewed from a distance, the colors blend together in the eye of the observer. It was developed by Georges Seurat in the 1880s as part of the Post-Impressionist movement. Other masters of Pointillism include Paul Signac, Charles Angrand, and Henri-Edmond Cross. Seurat's most famous Pointillist work is A Sunday Afternoon on the Island of La Grande Jatte.

Stringray report for nikki valovich
Stingrays are carnivorous bottom-dwelling fish that feed on a variety of prey found on or near the seafloor like mollusks, crustaceans, and small fish. They use their powerful jaws and teeth to crush shells and detect prey via electrical signals. Stingrays come in many sizes from small species less than a foot wide to large manta rays over 20 feet wide. They are found worldwide in tropical, subtropical and temperate coastal waters where they use their camouflage to ambush prey and hide from predators on the seafloor. Stingrays are known for their venomous tail spines which they use for defense when threatened.
3rdGradeReptilesandAmphibians.ppt
There are over 6,800 reptile species including alligators and crocodiles, turtles and tortoises, snakes, and lizards. Reptiles are ectothermic vertebrates with scaly skin and internal skeletons. They lay shelled eggs and undergo little development from hatching to adulthood. Amphibians include over 4,000 species of frogs, salamanders and caecilians. They are also ectothermic vertebrates but have permeable skin and undergo metamorphosis from aquatic young to terrestrial adults. Both groups shed their skin and use environmental heat to regulate their body temperature.

The sperm whale lives in pods in open oceans around the world. It is the largest toothed whale and has the largest brain of any animal. Sperm whales hunt giant squid by diving deep in the ocean. Females give birth every 3-5 years and calves nurse for up to 8 years. Sperm whales were heavily hunted for oil and other products in the 18th-20th centuries, greatly reducing their population before whaling was prohibited.

Crabs
Crabs are interesting animals that can live on land and in water. They have a wide body with ten jointed legs, with the front two legs having claws. Crabs breathe through gills like fish and have no internal bones. They run sideways and molt their shells to grow, carrying eggs under their stomachs until they hatch into larvae. Crabs are nocturnal hunters that eat debris on the ocean floor or use claws to open shells of other animals.
Sea turtle
Sea turtles
It is difficult to find the exact population numbers for sea turtles because male and young sea turtles do not return to shore once they hatch and reach the ocean, which makes it hard to keep track of them. However, all around the world countries have set up turtle sanctuaries. Take the Maldives, five of the seven species of sea turtles can be with the two most common being the Hawksbill and the Green Leatherback.
Animals and adaptation
Animals and Adaptation discusses how animals adapt both structurally and behaviorally in order to survive in their environments. It provides examples of structural adaptations like thick fur coats and behavioral adaptations like moving in large groups. The document then focuses on penguins, describing their structural adaptations like dense feathers and behavioral adaptations like huddling in large groups to stay warm. It notes that while penguins' structural adaptations help with things like insulation and camouflage, their behavioral adaptations of returning to the same breeding locations make them vulnerable to predators.

Vertebrates
- Most fish breathe through gills and have skeletons made of bone or cartilage. They propel themselves through water using tail fins and other fins. Fish come in a wide variety of sizes, from less than an inch to over 60 feet long.
- Reptiles are air-breathing vertebrates covered in scales that lay eggs. Examples are crocodiles, lizards, snakes, turtles, and tortoises. They are often cold-blooded and regulate temperature behaviorally.
- Birds are feathered flying animals with wings, beaks, and lightweight skeletons adapted for flight. Their respiratory and skeletal systems are specialized for flying.
Connorp finishedp3
Turtles are reptiles with a strong shell that protects their inner organs and backbone. They can live on land or in water, breathing air through a process called buccal pumping. Their shells come in different shapes depending on whether they live on land or in water. While most turtle species lay eggs, some turtle genders are determined by temperature during incubation. The alligator snapping turtle is one of the largest turtle species known for its size, spiked shell, and diet of fish and smaller animals.

Animals That Lay Eggs (with Pictures).pdf
Organisms have different methods of reproduction. To tell the truth, these different reproductive methods are the factors that divide animals into two categories: viviparous and oviparous animals. But more on that in a bit, here's a blog on the many different animals that lay eggs!
Do you want to know about animals that lay eggs?
Nature's way of maintaining the ecological balance on earth is something special. For example, Mother Nature has endowed living animals with the ability to go through the process of labor to directly give birth to their own kind.
Whereas, oviparous animals lay eggs that give birth to young as soon as they hatch.
Now, if you are stuck wondering because nature has allocated different reproductive processes to different animals, then we are just as clueless as you!
However, you can acknowledge the fact that every process created by nature is purposeful. For example, if nature has given birds the ability to lay eggs to produce their offspring, it may be for their own benefit.
The main reason for this is that birds cannot fly while carrying the weight of their young. By laying their eggs in a remote location, they thereby safeguard both themselves and their offspring.
We also understand how interested you are in learning about the ovoid animal species.
So, read on to know more about the complex egg-laying process and a description of the top 13 animals that lay eggs.
Animals That Lay Eggs
If we were to list all oviparous animals, you would get tired of reading the never-ending list!
A large number of prominent species in the animal kingdom are oviparous, including insects, birds, amphibians, reptiles, fish and even some mammals.
So, if you are ready to know about 13 animals that lay eggs, connect with us!
Birds
Birds are the first members of our list of animals that lay eggs. Birds are the most lively and colorful species of the animal kingdom, somewhat related to the ancient family of reptiles, the dinosaurs.
They are a very unique creation of nature because they are the only animals with feathers that are known to exist on Earth. These warm-blooded vertebrates are also known to be closest to reptiles due to the rough shape of their feet.
The largest birds alive today are the North African ostriches, which can reach 9 feet in height and weigh up to 350 pounds. The ostrich egg is the largest of any other bird species.
On the other hand, the smallest extant birds are Cuban native hummingbirds weighing less than 3 grams.
Also, the bird's feathers make them stand out among every other species.
However, having wings does not guarantee a bird's ability to fly. There are several flightless birds, including penguins, kiwis and ostriches, which, although they have wings, cannot fly due to some evolution that took place over the years.
Also, bird eggs have a hard shell that ensures safety and are laid in secluded areas like bird nests, such as a treetop or an abandoned room. The parents fulfill the responsibility of taking care it...

Tots and tails all about rabbits
Rabbits can live 5-10 years, grow to be 2-4 pounds, and eat hay, vegetables, and pellets. Their teeth constantly grow so they need hay to keep them worn down, they go potty in litter boxes, clean themselves by grooming, and have whiskers and large ears to help them navigate and sense their surroundings. They show happiness through behaviors like binkies, flops, and purring noises.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

Hermit crabs
- 1. Hermit Crabs
- 2. A hermit crab does not have its own hard shell.
- 3. It starts out as an egg which is laid in the ocean.
- 4. While in the ocean, the eggs hatch. At first, they look like brine shrimp.
- 5. They stay in the ocean growing slowly until they resemble their parents and can climb back on land.
- 6. Hermit crabs have soft stomachs or abdomens. They are easily gobbled up by birds or small animals as they come ashore.
- 7. Once on land, these tiny hermit crabs must find shelter or they will die.
- 8. So for protection, a hermit crab usually lives in a shell. It carries its home wherever it goes.
- 9. A hermit crab's soft body is naturally flexible and can twist easily to fit into the spiral interior of a snail’s shell
- 10. When it finds a shell, the hermit crab's abdomen forms to the shape of that shell. For most of its life, a crab will prefer shells with the same shape because it's comfortable for them.
- 11. Some species of hermit crabs live in the ocean. These particular crabs do not make good pets.
- 12. Most adult hermit crabs are from 1/2 inch (13 mm) to 4 3/4 inches (121 mm) long.
- 14. Hermit crabs are both herbivorous (plant eaters) and scavengers. In the wild, hermit crabs feed on animal and plant remains, overripe fruit and droppings from other animals.
- 15. Hermit crabs are crustaceans. All crustaceans have hard skin, gills and two pairs of antennae.
- 16. A hermit crab has round eyes on the end of eyestalks.
- 18. A hermit crab has five pairs of legs or ten legs in all. Not all of the legs are fully developed.
- 19. Only six legs show. These front six legs are known as walking legs.
- 20. Hermit crabs keep their four back legs inside their shell. The back legs are much smaller than the walking legs.
- 21. The front pair of legs ends in claws, or pinchers. The left front leg is usually larger than the right claw and has a large pincher. The crab uses this large pincher for moving around and defending itself.
- 22. When the crab is hiding inside its shell, it uses this pincher to seal off the shell’s opening. The right front leg has a smaller pincher, which the crab uses to eat and drink.
- 23. Some hermit crabs only live for 2-3 months, but some can live up to 20-30 years.
- 24. They have an exoskeleton, or outer skin, which they moult to grow.
- 25. Moulting is a process of shedding their exoskeleton so they can grow a little.
- 26. . How many times a crab moults depends on its size, health and habitat. If it is not living in ideal conditions it will moult less often and if it lives in a good habitat, it will moult whenever it feels like it.
- 27. Hermit crabs grow very slowly, only about a millimeter a year, so they will not need a new shell right after shedding their skin. Moulting has nothing to do with switching shells.
- 28. When a hermit crab does outgrow its shell, it switches to a larger one. Some species switch shells even if the shell still fits.
- 30. Hermit crabs seek out abandoned shells for protection from predators.
- 31. When a hermit crab finds one of the proper size, it pulls itself inside, leaving several legs and its head outside the shell.
- 32. Different hermit crabs like different kinds of shells, and they also enjoy “shopping” for shells. Hermit crabs will spend a lot of time checking out new shells
- 33. Shell changes take a matter of seconds, and depending on the species, can happen on an almost weekly basis or take months or years.
- 34. In places where discarded shells are hard to come by, hermit crabs may cover themselves with a coconut shell, a piece of bamboo, or anything else they may find.
- 39. Hermit crabs are nocturnal and are busiest at night. They are social creatures that do best when they live in groups.
- 42. In the wild, they may travel in packs of up to 100 crabs, scavenging the beach for food and shells.
- 43. If you choose to have a hermit Crab as a pet, remember they are social creatures. Your hermit crab will enjoy living with other hermit crabs. There are many books that can help you learn to set up the right environment and care for your new pet.
