Crustaceans emerge from eggs usually as a larval stage that looks nothing like the adult, but yes, they have shells.
Shell.
The process in which crustaceans shed their shell is a process called molting.
Gills, in the shell in molluscs, and between the hind legs in crustaceans.
Crayfish are crustaceans, and therefore have a shell-like outer covering called an exoskeleton.
Yes -- exoskeleton is an external skeleton, or shell. Crustaceans have this.
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.
Carapace is a dorsal upper section of the exoskeleton or shell in a number of animal groups, including arthropods such as crustaceans and arachnids. The function of the carapace is to protect the animal and act as shelter.
Yes, barnacles are crustaceans. They are marine arthropods that belong to the subclass Cirripedia, and they typically attach themselves to hard substrates, such as rocks or ship hulls, using a cement-like substance secreted by their bodies.
