Crab's that live on land and in water do not call their eggs anything special. Though pubic crabs call their eggs nits.
They are called Roe.
Shell.
The process in which crustaceans shed their shell is a process called molting.
Crayfish are crustaceans, and therefore have a shell-like outer covering called an exoskeleton.
Gills, in the shell in molluscs, and between the hind legs in crustaceans.
Not all of them have "shells," but all of them have exoskeletons, which are essentially the same thing.
Yes -- exoskeleton is an external skeleton, or shell. Crustaceans have this.
Crayfish belong to phylum arthropoda because they, like all arthropods, are characterized by segmented bodies, an exoskeleton made from chitin, and joint appendages. Crustaceans like crayfish, lobsters, and crabs are all arthropods.
They have a shell to protect their back.
Yes! A turtle is a crustacean because it has a shell! Crustaceans are animals with shells!
Crustaceans are animals that live in the Ocean. Their skin, is their outer-shell of a body, so it would be hard and thick.
Similarities: Daphnia and crustaceans (such as shrimp) share the same kind of "jerky" movement through a body of water. Also, like crustaceans such as lobsters and crabs, both have a hard outer shell.
Some examples include: shrimp, crab, lobster, barncles, and prawns.
