Crustaceans
Usually considered as a subphylum, Crustaceans comprise a group of arthropods including crabs, crayfish, lobsters and shrimp. Most crustaceans are aquatic animals, though some are terrestrial, parasitic and barnacles. Crustaceans have a chitinous exoskeleton, segmented body, and paired jointed limbs.

The "shell" of the crayfish, or rather its exoskeleton, is composed of the polysaccharide chitin and some lipids. There are also some calcium salts in the exoskeleton of the crayfish, which gives it its firmness.
What 2 systems of a crayfish are most unlike human systems?
Exoskeleton: Crayfish have a hard shell, and no bones. That makes crayfish invertebrates (no spine).
Gills: Crayfish respire underwater through gills, where humans use lungs.
The circulatory system is the second one, the reason for this being that crayfish have no blood vessels (and humans obviously do).

Don't throw them away they may be molting mine just molted. I thought he was dead but I kept him because he didn't fall out of his shell. He had white eyes. But I put him in the iso tank and he molted the next day, he was medium and it took three days. Be careful he is pink small and soft now and don't keep him with other crabs until he changes from his present shell they may eat him and don't throw his exo skeleton away he needs calcium.
Yes they do have bristles. They have three main places where they are at.In the Thorax the Abdomen And the Exopodite.
What four substances make up the exoskeleton of a crayfish?
The 4 substances are Lipids, Proteins, Chitin and Calcium Carborate.
Crabs use their powerful claws to access their food, via prising or pulling. They then use their pincers to snip the food up into small portions, before transferring it to their mouths human-fashion.
a small crab with around four legs, if you get pinched pour hot water (from sink) on it so it releases you: out; out of their shell shell they look like a shrimp with a claw. inside of their shell they lok like a spider i have hermit crabs so i know.

What animal classification group is the crayfish in?
To classify organisms, we use the five-kingdom system of classification. Obviously, the crayfish is not an amoeba-like organism or a single-cell organism. It is clearly not a plant, because it does not manufacture its own food, has a nerve cord and can move. Therefore it must be an animal. It is actually relatively complex as animals go. I know its classification to phylum level: Kingdom: Animalia - Animals.
Subkindgom: Metazoa - Animals with a digestive tract.
Phylum: Chordata - Animals with a neural tube. The crayfish, as a crustacean, is not a vertebrate, but it is still quite a complex animal.
