Crabs grow as the eat and mature. They molt their exoskeleton to allow for their increase in size. A shell dweller will also require a continuous supple of new and bigger shells as it grows.
Chitin, N-acetylgucosamine, makes up the exoskeletons of crustaceans.
Some crustaceans are omnivores.
No, cuttlefish are not crustaceans. They are a type of marine mollusk, related to squids and octopuses. Crustaceans are a separate group of arthropods that include animals like crabs, lobsters, and shrimp.
The shedding process of a lobster is called molting. During molting, the lobster sheds its hard exoskeleton in order to grow a new, larger one. This process allows lobsters to grow and regenerate damaged parts of their exoskeleton.
The nauplius larvae share characteristic features with other crustaceans, such as possessing one eye and three pairs of appendages. By observing these larvae in barnacles and tongue worms, scientists could classify them as crustaceans based on these shared traits. This discovery helped to place barnacles and tongue worms within the larger group of crustaceans.
True, that is the only way crustaceans can increase in size limited by their exoskeleton.
