Any aquatic invertebrate animals having a cutaneous or calcareous shell surrounding there body and belonging to the phylum Mollusca, the class Crustacea (phylum Arthropoda), or phylum Echinodermata is known as shellfish. The term is often used for the edible species of the groups, especially those that are fished or raised commercially. The most commercially important shellfish are:
• Mollusk: Oysters, mussels, scallops and clams
• Crustacean: Shrimp, prawn, lobster, crab and crayfish
• Echinoderm: sea urchins and sea cucumbers
Shellfish hatchery is a place where shellfish seeds are produced in a controlled way. Hatchery management is a branch of science which deals with the activities including from collection of brood shellfish to seed production. Culturing of shellfish has occurred since ancient times. Although controlled rearing of young shell has long existed, hatchery production is a more recent advancement. Producing seed under controlled conditions in a hatchery will disconnect its production from environmental factors and provide a reliable supply of seed. Oysters, mussels and mud crabs are the most important groups of shellfish after shrimp and prawn. These are popular among the western countries and becoming more popular all over the world. So hatchery management of oyster, mussel and crab is crucial.

A) Explain five (5) challenges amphibians faced when colonizing land.pdfarhamgarmentsdelhi
A) Explain five (5) challenges amphibians faced when colonizing land and how they solved
them. B) Explain the improvements reptiles evolved from the amphibian solutions (the five (5)
listed in the question above) to adapt to terrestrial environment
Solution
a) The terrestrial realm of land and air offers many challenges to organisms adapted to aquatic
life:
Gravity:aquatic life is buoyed by water.Air is not so buoyant! So terrestrial animals have to have
some sort of supporting tissue.Endoskeleton of bone and lobe fins modified to limbs.Also
changes in skeleton for land hunting - Shoulder free from skull to give head more flexibility and
arm greater lateral movement
Descication: air is drier than water,so terrestrial organisms need some form of skin or coat to
keep all their precious bodily fluids from leaking out.Fish scales don\'t protect the body much
against desiccation. Besides Amphibians lost those scales early in their evolution.Amphibians
never really solved the skin-permeability problem.They are restricted today to moist habitats.
Respiration: aquatic organisms exchange oxygen and carbon dioxide dissolved in water.In
air,these substances are gases,so new structures are needed to breath.Fish breathe the oxygen
dissolved in water through their gills.Out of the water,however,they are unable to survive for
more than a few minutes.In order to live on dry land,they need to acquire a pulmonary
system.They developed lungs inside body
and stronger rib cage.
Reproduction:aquatic organisms often release their eggs,sperm,etc.,directly into the water.This
approach is much less effective in air,so other solutions evolve.But there is no special
adaptation,return to water to mate.
Locomotion:aquatic animals can swim,scuttle,squidge,orotherwise move through the
water.These motions have to be modified in the terrestrial realm.
Senses:light,sound,and smell transmit differently in water than in air,and some senses don\'t
work in air at all.Terrestrial animals have to evolve new adaptations to deal with these
differences.Lateral line which senses vibrations under water becomes lost and an operculum
overlaying the lower jaw is used to sense vibrations in air.
Excretion:Due to the abundant water in their environment,marine creatures can immediately
filter and expel their bodies waste products,particularly ammonia.On land,water must be used at
minimum levels.For that reason these living things have kidneys,in which ammonia is filtered
out as urea and stored in the bladder,and the minimum amount of water is used when it is
expelled.In addition,there is a need for new systems that enable the kidneys to
function.Amphibians ability to conserve body water is rudimentary.Considerable water is lost by
evaporation through their skin.Most species excrete a copious and diluteurine because a large
volume of water is needed to flush out toxic excretory products through their kidney tubules.
b)Amniotic egg:Amphibians never succeeded in becoming fully terrestrial because.
WHAT ARE THE DIFFERENCES BETWEEN A SEA SNAIL AND A LAND SNAIL..docxGBENGANATUREFARMS
Snails are fascinating creatures found in a wide variety of environments, from terrestrial landscapes to the depths of the oceans. While they share a common basic structure and belong to the class Gastropoda, sea snails (marine snails) and land snails exhibit significant differences due to the distinct habitats they inhabit. In this discussion, we will delves into the various aspects that differentiate sea snails from land snails, including their physiology, habitats, diets, reproductive strategies, and adaptations………PLEASE WATCH THIS VIDEO CLIP TO PEER INTO THE WORLD OF SNAILS……….https://www.youtube.com/watch?v=8dz4Tln9Mz0&t=2s
1. Habitat and Environment
Sea Snails: Sea snails inhabit marine environments, ranging from shallow coastal waters to the deepest ocean trenches. They are found on rocky shores, sandy beaches, coral reefs, and hydrothermal vents. The saline nature of seawater influences their physiology and behavior, requiring specific adaptations to cope with varying salinity levels, water pressure, and the availability of oxygen.
Land Snails: Land snails live in terrestrial environments, including forests, grasslands, deserts, and gardens. They require a moist habitat to prevent desiccation, as they are prone to drying out. Consequently, land snails are often found in humid areas with abundant vegetation and shelter. They have evolved mechanisms to retain moisture and survive in fluctuating temperatures and humidity levels…………..AS SNAIL PET OWNERS YOU NEED TO LEARN TECHNIQUES IN CARING FOR YOUR SNAILS AS YOU WATCH THIS VIDEO CLIP…………..https://www.youtube.com/watch?v=8dz4Tln9Mz0&t=2s
2. Respiratory Systems
Sea Snails: Sea snails primarily use gills for respiration, similar to other aquatic animals. Their gills are located in a mantle cavity and extract oxygen from the water. Some sea snails, especially those in intertidal zones, have developed secondary breathing structures to tolerate periods out of water.
Land Snails: Land snails breathe air using a lung-like structure called a pallial cavity or mantle cavity, which acts as a primitive lung. This cavity opens to the outside through a small hole called the pneumostome. Land snails must keep this cavity moist to facilitate gas exchange, which is why they are often seen in humid environments……….ALL PET LOVER COMMUNITY WORLD WIDE, PLEASE JOIN ME AS WE WATCH THE AMAZING WORLD OF SNAILS TOGETHER,,PLEASE WATCH THIS CLIP……….https://www.youtube.com/watch?v=8dz4Tln9Mz0&t=2s
3. Shell Structure and Function
Sea Snails: The shells of sea snails are often more robust and varied in shape and size compared to land snails. They are built to withstand the pressures of the marine environment and protect against predators. Some sea snails, like the abalone, have shells with an iridescent interior, while others have spines or thick ridges.
Land Snails: Land snails typically have lighter and thinner shells, which are not designed to withstand the same level of pressure as those of sea snails.....

You could be a professional graphic designer and still make mistakes. There is always the possibility of human error. On the other hand if you’re not a designer, the chances of making some common graphic design mistakes are even higher. Because you don’t know what you don’t know. That’s where this blog comes in. To make your job easier and help you create better designs, we have put together a list of common graphic design mistakes that you need to avoid.
Book Formatting: Quality Control Checks for DesignersConfidence Ago
This presentation was made to help designers who work in publishing houses or format books for printing ensure quality.
Quality control is vital to every industry. This is why every department in a company need create a method they use in ensuring quality. This, perhaps, will not only improve the quality of products and bring errors to the barest minimum, but take it to a near perfect finish.
It is beyond a moot point that a good book will somewhat be judged by its cover, but the content of the book remains king. No matter how beautiful the cover, if the quality of writing or presentation is off, that will be a reason for readers not to come back to the book or recommend it.
So, this presentation points designers to some important things that may be missed by an editor that they could eventually discover and call the attention of the editor.

2. SHARKSKIN = SWIMSUIT
Sharkskin-inspired swimsuits received a lot of media
attention during the 2008 Summer Olympics when the
spotlight was shining on Michael Phelps.
Seen under an electron microscope, sharkskin is made up of
countless overlapping scales called dermal denticles (or
"little skin teeth"). The denticles have grooves running down
their length in alignment with water flow. These grooves
disrupt the formation of eddies, or turbulent swirls of slower
water, making the water pass by faster. The rough shape also
discourages parasitic growth such as algae and barnacles.
Scientists have been able to replicate dermal denticles in
swimsuits (which are now banned in major competition) and
the bottom of boats. When cargo ships can squeeze out even
a single percent in efficiency, they burn less bunker oil and
don't require cleaning chemicals for their hulls. Scientists
are applying the technique to create surfaces in hospitals
that resist bacteria growth — the bacteria can't catch hold
on the rough surface. LOTUS = PAINT
The lotus flower is sort of like the sharkskin of dry land.
The flower's micro-rough surface naturally repels dust and
dirt particles, keeping its petals sparkling clean. If you've
ever looked at a lotus leaf under a microscope, you've
seen a sea of tiny nail-like protuberances that can fend off
specks of dust. When water rolls over a lotus leaf, it
collects anything on the surface, leaving a clean leaf
behind.
A German company, Ispo, spent four years researching
this phenomenon and has developed a paint with similar
properties. The micro-rough surface of the paint pushes
away dust and dirt, diminishing the need to wash the
outside of a house.
