There are a huge number of differences between a crab and a fish including the fact that most fish do not have a hard shell or carapace while most crabs do have this type …of covering. Crabs also have legs and claws while fish do not have those appendages.
A hermit crab uses the old shell of another sea animal (ex. snail). I true crab uses its own natural shell. A hermit crab makes its home in a snail shell or a…nything really. It has a soft abdomen that is very vulnerable to the outside and can be smooshed easily almost like a caterpillars skin. So it hides its back end in a protective covering. A regular crab already has its own exoskeleton that is hard and durable so they don't need a shell to protect them. Also, regular crabs live in the water a majority of the time and a hermit crab can either be completely dependent on water, these are called saltwater hermit crabs who live like a fish at the bottomof the ocean, or you have a typical land hermit crab that lives on the beaches and sometimes even a mile off shore. They do not need a large amount of water or food to survive. These are the crabs you find in the pet store in the fancy painted shells.
fish have gills crabs dont! Crabs have claws fish dont.
sharks - have rows of teeth, no scales, can't stop swimming & can't swim backwards, need constant water flow over gills, cartilage - no bone, oily liver instead of a swim …bladder, can sense electricity (ex:heart beat) & vibrations in water, gill slits - no gill cover, eggs fertilized inside females body. fish - 1 set of teeth or none at all, can hover & swim backwards, most are bony, swim bladder, can't sense electricity, covered gill slits, eggs usually fertilized in water.
a frog is a anfibian and a crab is a carnation
The Crab Nebula is a nebula.
llobster has a hard back and shrimp is a little cruly fish thingy that moves in the water
Most crabs have shells, but the hermit crab is a type of crab that doesn't. Instead, they adopt discarded mollusc shells such as whelks and periwinkles, and use their shell.
crabs and scorpions both have claws and pincers. and the difference between them is crabs dont have stingers on the back but scorpions do
A fish has gills and fins, which frogs dont Fish are groouped in fishes while frogs are anphibians.
both have 10 legs , but , lobster's the front three pairs bear claws , and crab's front two legs sometimes use for walking but mostly for eating.....
A crab has a round body where a lobsters body looks alot more like a giant shrimp with big pincher's crabs also have pincher's too! When you boil a crab it becomes distressed… and poises its meat. Also when you boil a lobster it is blue when you put it into the pot/saucepan and pink when it comes out.
Crabs have shells. Starfish have 5 legs.
im not sure what the exact answer is but crabs aren't mammals. They are both crustaceans, class malacostraca Crabs and Crayfishes both belong to phylum arthropoda and the sam…e class known as Crustacea (hard exoskeletons). The only difference between them can be that crabs are a bigger version of crayfishes and they are able to live both in water and land but crayfishes are only marine. Hope that helps
in the group, all the fish are of the same species = use "fish" in the group, the fishes are of different species = use "fishes" Fish is used as plural and singular. However…, Fishes is used to refer to multiple species of fish.
crab 1. eyes of the crab are quite small. 2. they enable the crab to look all around. 3. the crab can sense even if the enemy approaches from behind. butterflies 1. butt…erflies has a large eyes that seem to be made up of thousand of littel eyes. 2. they can see not only in the front and the sides but back as well.
Fish are a type of animal. Mammals have internal lungs similar to humans with which they breathe. Fish have external gills so they can breathe underwater. They also have dif…ferent skeletal compositions, allowing animals to walk on land and fish to be buoyant under water.
