Tough waterproof outer covering that protects supports and helps prevent evaporation of water from the body of many invertebrates

A structural support system within the body of an animal

The basic definition of an invertebrate

An invertebrate is an animal without a backbone

The main eight groups of invertebrates

The main invertebrate groups are sponges, cnidarians, flatworms, roundworms, segmented worms, mollusks, arthropods, and echinoderms

Sponges are asymmetrical invertebrates that have some specialized cells but no tissues or organs. They take food into their body to get energy. ]wAdult sponges stay in one place.

Cnidarians are invertebrates with stinging cells that take food into a central body cavity. They have no organs, but some tissues..

Flatworms are worms with flat, soft, bodies. Some have eye spots on their heads that detect light.

Ground worms are worms that look like smooth, thin, tubes and have two body openings: a mouth and an anus.

Mollusks are invertebrates with soft, unsegmented bodies that are often protected by a hard shell. All mollusks have a thin layer of tissue called a mantle that covers their internal organs and an organ called a foot. Depending on the type of mollusk, the

In Arthropod is in invertebrate with a hard outer coating, a segmented body, and pairs of jointed appendages, such as legs wings, and antennae.
