The Invertebrates unit explores six groups of invertebrates— poriferans (sponges), cnidarians (such as sea jellies and corals), echinoderms (such as sea urchins and sea stars), mollusks (such as octopuses, snails, and clams), annelids (worms), and arthropods (such as insects, spiders, and lobsters).

What are the 8 classifications of invertebrates?

What are the 4 major characteristics of invertebrates?

Invertebrates share four common traits:

• They do not have a backbone.
• They are multicellular.
• They have no cell walls, like all other animals.
