The eight types of invertabrates are
Echinodermata - sea stars, sea urchins, sea cucumbers
Arthropoda - insects, arachnids, crustaceans
Nematoda - round worms
Mollusca - squid, snails, bivalves
Annelida - segmented worms (earthworms, leeches, polychaetes)
Platyhelminthes - flat worms
Rotifera
Acoelomorpha
Ctenophora -- Comb jellies
Cnidaria - jellyfishes, corals, sea anemones, hydras
Porifera - sponges
the phylums are porifer(sponge),cnidaria(jelly fish),platyhelminths(tape worms),nematoda(hook worms),annelida(leach),arthropoda(Spiders),echinodermta(seastar),and mollusca(snail and claims)
3 of the water invertebrate groups are the annelids, arthropods and crustacean.

One of the characteristics of many invertebrate groups is that there bodies are made of very many segments. Examples include the worms, spider, starfish and insects.
Well its sort of confusing, see since the invertebrate group has more groups than the vertebrate than that means invertebrate would have more organisms.
The eight groups are:* Mollusks * Echinoderms * Arthropods * Annelids * Nematodes * Porifera* Platyhelminthes * Coelenterates Or go to:What_are_the_8_groups_of_invertebrates
An invertebrate is an organism that lacks a backbone. The 6 groups of invertebrates are sponges, cnidarians, worms, mollusks, echinoderms and arthropods.
Arthropods' bodies are segmented into three parts. The head, the thorax, and the abdomen
The horseshoe crab is an example of an animal that has both vertebrate and invertebrate features. It has a hard exoskeleton like an invertebrate, but also possesses a primitive form of a segmented backbone similar to vertebrates.
The length of an average butterfly tends to be between 8 to 12 inches. Each butterfly species will have a different invertebrate length.
