The exoskeleton contains and protects the inner vital organs. It is usually made of chitin in insects and crustaceans, and of calcium carbonate in shellfish. There is a downside for a creature that is constantly growing: it has to enlarge its outer shell, or discard it and grow a new one, and it is vulnerable until the replacement shell is completed and hardened.

Which of these has an exoskeleton arthropod worm vertebrate cnidarian?
An arthropod
What keeps an arthropod from drying out?
The exoskeleton
What are the features of a arthropod?
exoskeleton, chitin, molting
What process does an arthropod sheds its exoskeleton to grow a new one?
an arthropod sheds it old exoskeleton when it has grown to a point where it needs a larger exoskeleton. This process is called ecdysis.
What happens to an arthropod's exo skeleton as the arthropod grows up?

What happens when an arthropod grows and its exoskeleton doesn't?
they shed thier exoskeleton for a new one
How does an arthropod grow larger?
Through shedding their exoskeleton.
What is a trait for an arthropod?
Arthropod traits include segmented bodies, an exoskeleton made from chitin, and joint appendages.
What happens to the exoskeleton when an arthropod grows?
Because of the hardness and inflexibility of the arthropod exoskeleton, they are not suited to expansion and need to be shed or discarded entirely to allow the arthropod to grow. This action is usually called moulting.
What is an arthropod's tough outer covering called?

Does every arthropod have an exoskeleton?
Yes, all arthropods have exoskeletons
