Detailed explanation-1: -The exoskeleton is a hard protective shell that covers and protects the animal’s body. Exoskeletons are seen in invertebrates that lack a backbone. Insects, crustaceans, as well as the shells of some sponges and the numerous families of shelled molluscs, all have exoskeletons.

Detailed explanation-2: -The exoskeleton is the hard outer shell (nonliving layer) of an insect, in contrast with the endoskeleton of humans and other mammals.

Detailed explanation-3: -Crabs, lobsters, shrimp, barnacles and many other animals belong to the phylum arthropods. In fact, 75% of all animals belong to the phylum arthropoda (which also includes spiders and insects). All arthropods have a hard exoskeleton made of chiton, a type of protein.

Detailed explanation-4: -An exoskeleton is a key feature of arthropods, a category of animals that includes insects, spiders, and crustaceans. Grasshoppers, cockroaches, ants, bees, cicadas, scorpions, lobsters, shrimp, black widows, snails and crabs are all examples of animals with exoskeletons.

Detailed explanation-5: -Arthropod Armor In arthropods, the nonliving exoskeleton is like a form-fitting suit of armor. It is produced by the “skin” and then hardens into a protective outer-covering. This exoskeleton is handy in some ways (it provides protection and prevents water loss), but is limiting in others.
