Amphibians are a diverse group of over 4,800 species including salamanders, frogs, and caecilians. They typically have a two-part lifecycle with an aquatic larval stage and terrestrial adult stage. Amphibians can live on both land and water and are found in a variety of habitats from deserts to rainforests, as long as it is damp. They have evolved adaptations like permeable skin, three-chambered hearts, and the ability to regenerate limbs that allow them to thrive on land and in water.

Parental care in amphibian
Amphibians show various forms of parental care to protect their eggs and offspring. This includes constructing nests or shelters to house eggs, directly coiling around or carrying eggs, giving birth to larvae, or retaining eggs in pouches or internally until the offspring are fully developed. Some frogs build mud or foam nests, while others lay eggs on leaves overhanging water. Certain frogs carry eggs on their backs or transfer tadpoles to water. Salamanders may coil around eggs or carry them attached to their neck. Parental care benefits offspring by increasing survival when they are associated with parents and improving offspring quality to boost future survival and reproduction.
Parental care in Amphibians
Parental care in amphibians provides benefits to offspring survival. There are various types of parental care exhibited by different amphibian species, including selecting protected nesting sites, defending eggs or territories, directly transporting tadpoles to water, gluing or carrying eggs attached to the body, and even viviparity in some species. Parental care improves offspring chances of survival by protecting eggs from predators and ensuring young amphibians safely reach water once hatched.
Parental care in amphibia
Amphibians display a wide range of parental care behaviors. Some female salamanders carry eggs attached to their neck until hatching. Frogs and toads also provide care, with some species gluing eggs to leaves or building mud nests. The male Darwin's frog cares for tadpoles by carrying them in his vocal sacs until they emerge fully developed.
Parental care in amphibians
Amphibians exhibit two main types of parental care: protection of eggs/young through nests/shelters, and direct caring behaviors. For protection, many frogs lay eggs near water in moist habitats and defend the eggs or territories. Some frogs have direct development where eggs hatch into small frogs. Others make foam, mud, or gelatinous nests. For direct care, some species coil around eggs, transport tadpoles to water, glue eggs to their bodies, carry eggs on their backs, or use vocal sacs or viviparity to brood eggs. Parental care helps offspring develop and avoid predators until independence.
Parental care in amphibia
Parental care in amphibians involves both protection of eggs and direct caring behaviors. Protection includes selecting safe egg-laying sites like under stones or in foam nests, while direct care involves behaviors like transporting tadpoles to water, carrying eggs attached to the body, or in pouches on the back or in organs. Some species even exhibit viviparity where eggs develop internally and receive nutrients via a primitive placenta. Overall, amphibians display a wide diversity of parental care behaviors to protect offspring and increase their chances of survival.
Parental care in amphibia
This document summarizes parental care behaviors in amphibians. It discusses how amphibians protect their eggs and offspring in two main ways: 1) by constructing nests, nurseries or shelters like mud nests, foam nests, and tree nests, and 2) through direct nursing behaviors like transporting tadpoles, protecting eggs on their bodies, and carrying egg clusters. Some frogs and toads build elaborate nests and carry out brooding behaviors to shelter eggs and developing young from harm until they are able to survive independently. Parental care is well-developed in amphibians due to its importance for offspring survival and propagation of their genes.
Parental care in amphibians and reptiles
Any form of parental behavior that appears likely to increase the fitness of the parent’s offspring.
Parents of some animals go to great lengths to increase their offspring’s survival prospects by protecting them from predators, food shortages, desiccation, and a range of other environmental hazards.
First off all they decide the oviposition site.
Any place where small puddles of still water form can provide a suitable nesting site. Sites range from potholes, tapir tracks, and large leaves to human made ditches, road ruts, and even plastic bowls
Rheobatrachus females brooded tadpoles in their stomachs, and the young emerged from the females
In case of moor frogs, males stay to guard the clutch. They attack anyone who
approaches it! They do not leave the post until tadpoles hatch. Only then, starving fathers
go to land and may eat well.
Parental care in amphibians
Parental care is common among amphibians, with 18% of salamander species and 6% of frog and toad species receiving care from both parents. Amphibians exhibit various forms of parental care including building nests, transporting tadpoles, carrying eggs attached to their bodies, and giving live birth (viviparity). In frogs, parental care involves nest building and guarding of eggs, transporting tadpoles, or carrying eggs in pouches or stomachs. In salamanders, both parents may coil around and guard eggs or exhibit viviparity by retaining young in the uterus until metamorphosis. While methods vary across the three amphibian classes, parental care helps increase offspring survival.

Presentation on Parental care in Amphibians
This document summarizes various forms of parental care exhibited by amphibians. It describes how amphibians select sites for egg-laying, form foam, mud, leaf, and shoot nests, carry eggs on their bodies, use organs as brooding pouches, coil around eggs, and transfer tadpoles to water. Some amphibians exhibit viviparity where young are born live rather than from eggs. The document concludes that parental care in amphibians likely evolved in response to their habitats and lifestyles, and may be instinctive rather than influenced by hormones.
Parental care in amphibians
This document discusses various forms of parental care exhibited by amphibians to increase offspring survival. It outlines nine types of parental care observed in amphibians: 1) selection of safe egg-laying sites, 2) frothing of water around eggs, 3) defending egg territories, 4) building nests from mud, leaves, or plant shoots, 5) direct development from egg to juvenile, 6) carrying eggs attached to the body, 7) carrying larvae between water bodies, 8) brooding eggs in vocal sacs or pouches on the back, and 9) retaining eggs internally in a uterus for viviparous development.
Parental care in fishes
Parental care is any behavior pattern in which a parent invests time or energy in feeding and protecting its offspring.
Parental care is a form of altruism since this type of behaviour involves increasing the fitness of the offspring at the expense of the parents.
The evolution of parental care is beneficial as it facilitates offspring performance traits that are ultimately tied to offspring fitness.
Parental care is evolved in those organism which produce limited no. of eggs to ensure the continuity of their race.
Parental care in fishes By TANZEEBA AMIN
Parental care is an important behavior for perpetuating fish species. Many fish species care for their eggs and young in various ways. Some fish build different types of nests, such as circular, basin-shaped, or barrel-shaped nests to lay and care for eggs. Other fish deposit eggs in suitable locations or carry them in their mouths or pouches. Some fish are viviparous. Parental care benefits offspring survival but increases costs to parents. There is great diversity in parental care strategies among fish species.

Reproductive strategies in fishes
This document summarizes different reproductive strategies in fishes. It discusses that most fishes are oviparous and lay eggs externally. For marine fishes, the majority have pelagic eggs that float, while demersal eggs that sink are more common in freshwater. Some fishes are ovoviviparous or viviparous with internal fertilization. Different forms of parental care among fishes are also outlined, including by the male, female or both parents. Alternative reproductive strategies discussed include hermaphroditism, parthenogenesis, and natural polyploids and hybrids.
Parental care of fishes
Parental care in fishes ranges from simple nest building to carrying eggs and live birth. Some common types of parental care seen in fishes are nest building like bubble nests and weed nests. Other fishes attach eggs to their bodies like pipefish and sea horses where males carry fertilized eggs in brood pouches. Mouth brooding is also common where parents incubate eggs in their mouths. Some sharks and rays enclose eggs in leathery mermaid's purses. The highest level of care is viviparity where young develop internally and receive nourishment from a placenta.
Reptile reproduction and diseases
Reptiles reproduce through three main methods - oviparity where eggs are laid and hatch externally, viviparity with live birth, and ovoviviparity where eggs are retained internally and hatch within the mother's body. Turtles lay eggs in nests with no parental care, while snakes may be oviparous, ovoviviparous, or viviparous. Lizards also use these three reproduction methods and females exhibit dimorphism. Crocodilians are solely oviparous, building nests and providing parental care until hatching.
"parental care of harvivore animals "seminar by Subrata paul
This document discusses parental care in herbivorous mammals. It describes how parental care varies between species, with females generally providing most of the care since males contribute little after mating. The types of parental care include maternal, paternal, and biparental care. Examples are given for several species like hippopotamus, giraffe, gorilla, and okapi. Benefits of parental care include improved offspring survival. There can also be conflicts between parents and offspring over the level and duration of care provided.

Behavioural ecology of fishes
This document outlines various behaviors studied in behavioral ecology, including feeding behavior, predation, parasitism, mutualism, and communication. It discusses how feeding behavior is regulated by environmental and homeostatic factors. Predation behaviors in different fish species are described, as well as how predators and prey can control each other's populations. Competition between species and intraspecific competition are examined, including examples of resource partitioning and differential exploitation. The document also summarizes symbiotic relationships like mutualism, commensalism, and parasitism in fish, and covers behaviors like migration, schooling, camouflage, and sound/chemical communication.
Fish reproduction
There are four main types of fish reproduction: live-bearing, ovoviviparous, viviparous, and oviparous. Live-bearing includes mouth-brooding fish that incubate eggs in their mouths. Ovoviviparous fish hatch eggs internally that are then birthed, viviparous fish nourish embryos internally, and oviparous fish lay eggs that develop externally in water. Successful fish farming requires carefully monitoring conditions for egg-laying and live-bearing species.
Parantal care in fishes
Parental care in fishes involves various behaviors to protect eggs and offspring. Many fish build elaborate nests, such as sunfish creating shallow basin nests. Others guard eggs in their mouths or coil around them. Parental care increases survival chances for offspring and helps continue species. Behaviors seen include nest building, guarding eggs, and caring for hatchlings. Parental care is an important evolutionary development for fish reproduction.
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.

Frogs play an important role in ecosystems by controlling insect populations, serving as a food source, and facilitating nutrient cycling between aquatic and terrestrial environments. However, many frog species are now threatened by habitat loss, climate change, and the deadly chytrid fungus. The document outlines efforts to conserve endangered frog species in Haiti and the Dominican Republic through long-term monitoring programs, developing management guidelines, educating local communities, and establishing captive breeding populations. The goal is to prevent extinction of endemic frogs and protect the forest habitats in which they live.
Amphibian Defense Notes
The document discusses several means of defense used by amphibians, including producing toxic chemicals from skin glands, mimicry of poisonous species, warning coloration, hiding behavior, rapid escape, urination when grasped, and emitting a distress call when captured. Specifically, it notes that frogs and toads can release bufotenin from parotoid glands or that newts produce the lethal toxin salamandrin.
Phylum Chordata - Class Amphibia
Amphibians were the first vertebrates to live on land but still require water to reproduce. They developed lungs, legs, and moist permeable skin to survive out of water. Amphibians include frogs, toads, salamanders and caecilians. Many amphibian populations are declining due to threats like climate change, habitat loss, pollution and disease.
Phylum Chordata (PowerPoint Presentation)
This document summarizes the key characteristics of the phylum Chordata. It outlines the three subphyla of Chordata - Urochordata, Cephalochordata, and Vertebrata. The classes within Vertebrata are then described, including Cyclostomata, Chondrichthyes, Osteichthyes, Amphibia, Reptilia, Aves, and Mammalia. For each class, key distinguishing anatomical and physiological traits are identified.
Honey Bee Presentation Final
Honey bees are crucial pollinators for many fruits and vegetables. They pollinate about 30% of the food consumed in the US. However, honey bee populations have declined by 30-50% over the last 20 years due to various factors like pesticides, malnutrition, mites, and viruses. If honey bee populations continue to decline, it could significantly impact food prices and availability. There are steps people can take to help honey bees, such as planting bee-friendly gardens and donating to research on solving colony collapse disorder.

Amphibia[1]
Class Amphibia includes over 5,400 species of caecilians, salamanders, frogs, and toads that typically live near water. Many amphibian species are threatened due to habitat loss and other causes. Amphibians have permeable skin that aids respiration and protection, and powerful hind legs that allow them to leap long distances.
Amphibians
Amphibians are vertebrates that spend part of their life in water and part on land. They evolved from lobe-finned fish around 350 million years ago. Amphibians have adaptations for both aquatic and terrestrial environments like the ability to hibernate, estivate, and lay eggs in water that hatch into larvae. Common types of amphibians include frogs with short bodies and long back legs for jumping, toads with thick warty skin that live on land, and salamanders with slender bodies that hide under debris.
Vertebrata
This document summarizes the key characteristics of vertebrates. It discusses that vertebrates have an internal skeleton and true vertebral column, allowing for different muscle attachment points. They are bilaterally symmetrical and have features like a notochord, dorsal nerve cord, and paired gill pouches. Vertebrates are grouped into five classes - Agnatha, Chondrichthyes, Osteichthyes, Amphibia, Reptilia, Aves, and Mammalia. Each class possesses distinct skeletal structures and anatomical features that define their phylum and allow for different habitats and behaviors.

This document provides a detailed taxonomy, physiological characteristics, behaviors, diet, reproduction, and species information about crocodiles. It describes how crocodiles are large reptiles that live throughout tropical regions and maintain their body temperature through behavioral means. They are ambush predators that hunt both in water and on land, eating fish, birds, mammals and more. Crocodiles reproduce through mating in water and females laying hard-shelled eggs in nests. There are several crocodilian species described in detail.

Amphibians.
Amphibians were the first vertebrates to adapt to life on land around 350 million years ago. They preceded plants and insects. While not fully land-adapted, amphibians fill an important evolutionary niche between fish and reptiles. The earliest amphibians arose from lobe-finned fish and had characteristics like strong fins that helped with movement on land. Amphibians later diversified into three main orders - frogs/toads, salamanders/newts, and caecilians - adapting to both aquatic and terrestrial environments.
Brief Details of Vertebrata class 9
This document provides information about vertebrates and their classification. It discusses the five main classes of vertebrates: fish, amphibians, reptiles, birds, and mammals. For each class, it describes key distinguishing characteristics and provides examples of orders, families, and species within each class to illustrate vertebrate diversity. The document also contains diagrams and images to enhance understanding of vertebrate anatomy and biology.
Amphibians and reptiles
Amphibians live both on land and in water, having thin skin that allows absorption of water and oxygen. They go through a metamorphosis where larvae with gills transform into adults with lungs on land. While amphibians were the first to move onto land, reptiles later evolved with thicker scaly skin and shells for their eggs, allowing full adaptation to life on land.
Amphibian history notes
The document discusses the characteristics and evolution of amphibians. It notes that lobe-finned fish were ancestors of amphibians, which allowed them to move between bodies of water. There are approximately 4,000 known amphibian species classified into three orders. Amphibians are characterized by their permeable skin, three-chambered hearts, and typically having an aquatic larval stage before transforming into terrestrial adults.
phylum Chordata
This document provides an overview of the phylum Chordata, which includes animals with a notochord, dorsal nerve cord, pharynx with gill slits, and postanal tail at some point in their lifecycle. It describes the three subphyla: Urochordata (tunicates), Cephalochordata (lancelets), and Vertebrata (jawless and jawed fish, amphibians, reptiles, birds, and mammals). Key characteristics and examples are given for each class within these groups.
Aquatic mammals
Marine mammals have adapted physical characteristics that allow them to thrive in aquatic environments. They have thick layers of blubber for insulation, streamlined bodies for efficient swimming, and physiological adaptations like storing oxygen to stay submerged for long periods. The document then describes the distinguishing features of various groups of marine mammals including whales, seals, sea otters, polar bears, and manatees.
Fishes
This document summarizes key characteristics of chordates and classes of fish, including jawless and jawed fish. It describes:
1) The five characteristics of chordates and the classes of jawless fish (hagfish and lamprey), which have cartilaginous skeletons and sucker-like mouths.
2) The class Chondrichthyes (sharks and rays), which have cartilage skeletons, dermal placoid scales, and multiple rows of replacement teeth. Reproduction includes live birth and egg-laying.
3) The class Osteichthyes (bony fish), which have over 30,000 species with bony backbones, fins, and swim bladders.

Invertebrates presentation
Vertebrates are animals that have backbones. They are mostly found living on land or in water. Vertebrates are divided into fishes, amphibians, reptiles, birds, and mammals. Fishes live in water and have gills, scales, fins and lay eggs. Amphibians can live on land and in water, going through metamorphosis from an aquatic larval stage to a terrestrial adult stage. Reptiles live on land, have scales, and lay shelled eggs. Birds are adapted for flight with feathers and wings, and have high body temperatures. Mammals are warm-blooded with fur or hair, breathe air, feed their young milk, and most give
Amphibians
Amphibians are vertebrates that live in water as larvae and on land as adults. They have moist skin without scales or claws. There are three types of amphibians: salamanders, frogs and toads, and caecilians. Amphibians evolved to live partially on land by developing stronger bones, lungs, and breathing tubes. They can breathe through their skin but some live on land for more available food. Amphibians have external fertilization and undergo metamorphosis from embryo to adult. Frogs jump while toads prefer land. Salamanders and newts have different skin textures. Axolotls never develop lungs while caecilians resemble worms and live underground.
Aquatic vertebrates
This document describes several aquatic vertebrates including fish, amphibians, and reptiles. It provides details on the appearance, eating habits, life cycles, and other characteristics of different species of carp, catfish, fresh bream, frogs, snakes, and grass snakes. Fish generally have scales, fins, and gills and reproduce by laying eggs. Amphibians begin their lives in water with gills and tails, then develop lungs and legs to live on land as adults.
Vertebrates
Esta presentación ha sido elaborada para alumnos de 5º de Educación Primaria, en el área de Ciencias de la Naturaleza (Science). Con ella, podrán conocer los diferentes tipos de vertebrados que existen y poder estudiarlos de una forma motivadora y sintetizada.
Reptiles
Reptiles were the first terrestrial vertebrates and dominated during the Mesozoic era. There are around 7,000 reptile species worldwide today, with the most successful group being squamates (snakes and lizards). Reptiles are characterized by scaly skin, laying amniotic eggs, and various anatomical adaptations for living on land such as efficient lungs and kidneys. The four surviving orders are squamates, crocodilians, turtles, and the tuatara; turtles are notable for their protective shells.
