A hydrostatic skeleton or hydroskeleton is a structure found in many cold-blooded organisms and soft-bodied animals consisting of a fluid-filled cavity, the coelom, surrounded by muscles. Some examples are soft bodied animals such as sea anemones and earthworms. Hydrostatic skeletons have a role in the locomotion of echinoderms (starfish, sea urchins), cnidarians (jellyfish), annelids (earthworms), nematodes, and other invertebrates. They have some similarities to muscular hydrostats.
Yes, corals are composed of an exoskeleton
The bodies of arthropods are supported by a hardened exoskeleton made of chitin, a substance produced by many non-arthropods as well. In arthropods, the nonliving exoskeleton is like a form-fitting suit of armor.
The antonym of exoskeleton is endoskeleton. An endoskeleton is an internal skeleton found in vertebrates, whereas an exoskeleton is an external skeleton found in arthropods and some other invertebrates.
Exoskeleton.
A lobster's exoskeleton is a hard, protective outer layer made primarily of chitin, a tough and flexible protein. This exoskeleton provides structure and support for the lobster's body, as well as protection from predators and environmental elements. Lobsters periodically shed and regenerate their exoskeleton as they grow.
An arthropod
Earthworms are covered by a thin skin called epidermis. The epidermis is covered with a thin, protective cuticle that must be kept moist to permit the passage of oxygen through it.
Correct conclusion:Earthworm did not have any outer coverings. The outer skin of the worm is slimy to the touch, since it requires moisture in order to survive. The worm breathes through its skin.Wrong conclusion:Earthworms have a outer covering of scales.
No, an exoskeleton is a hard skeleton that sits on the outside of a eukaryote to protect and shape them, often in bugs, such as beetles. Worms are invertebrates, so they do not have an internal skeleton either.
they have exoskeleton
Yes; many cnidarians have an exoskeleton.
A butterfly has an exoskeleton. The exoskeleton appears when the caterpillar undergoes the metamorphosis process. It is the pup that dissolves and becomes the exoskeleton.

Insects infact don't have spines, instead they have a exoskeleton, meaning their skeleton is on the exterior of their body. Animals mainly do not have backbones because they basically don't need one to survive/live.
A cockroach has an exoskeleton which makes it more difficult to stick the pin through its surface and earth worm is just skin like a human being.
A very small worm-like bug can be distinguished from other insects in its habitat by its slender body shape, lack of distinct body segments, and soft, flexible exoskeleton. Additionally, these bugs typically move in a wriggling motion similar to a worm, rather than walking or flying like other insects.
