As such, the only animals on the planet that utilize a rigid endoskeleton are the ones that have a spine: humans, lizards, birds, frogs, bony fishes, and sharks (cartilaginous endoskeleton). Animals with exoskeleton have a head and abdomen and in some cases, a thorax. As well as supporting and protecting the creature, an exoskeleton also creates a watertight barrier that prevents the animal from drying out. Grasshoppers, cockroaches, ants, bees, cicadas, scorpions, lobsters, shrimp, black widows, snails and crabs are all examples of animals with exoskeletons. The word exoskeleton comes from name of the rigid, external skin of invertebrate animals (bugs, spiders, crabs, etc) which allows their body to keep its form without an internal skeleton.

This type of exoskeletons are further differentiated by what they are designed to do. The earliest terrestrial arthropods were probably millipedes. In all arthropods, the immature form of a given species, called a larva, undergoes metamorphosis at some stage in its life cycle to become an adult (the most famous example is a caterpillar turning into a butterfly). All have endoskeletons. All species assigned to the suborder Olenellina, that became extinct at the very end of the Early Cambrian (like Fallotaspis, Nevadia, Judomia, and Olenellus) lacked facial sutures.

This is because large animals could not be supported by exoskeleton and need bones to support them. PLAY. Echinoderms exhibit the presence of tube feet all over their body, and a water vascular system (WVS) runs internally along the body wall, from the mouth all the way to the tip of these tube feet. the animal emerges and swells to a larger size until the newer, larger exoskeleton is hardened. Most animals have an exoskeleton, including insects, spiders, scorpions, horseshoe crabs, centipedes, and crustaceans.

Animals with exoskeletons like arthropods (a class of animals including insects, crustaceans and arachnids) transitioned from sea to land long before the vertebrates (organisms with endoskeletons). The global animal kingdom includes species with external skeletons, called exoskeletons, and organisms with internal skeletons, called endoskeletons. They are all invertebrate animals. The exoskeleton is confined to animals such as insects, spiders, scorpions, crabs etc., all of which belong to the Phylum Arthropoda (jointed-legged and jointed-bodied animals). While exoskeletons are the norm for both these classes of animals, they have different overall compositions. Arthropods lack locomotory cilia, even in the larval stages, probably because of the presence of the exoskeleton. Shelled mollusks include snails, tusk shells, clams, nautilus and chitons.
