You can chop off a piece of then and not only will they survive, but grow a new one!
The eight groups are:* Mollusks * Echinoderms * Arthropods * Annelids * Nematodes * Porifera* Platyhelminthes * Coelenterates Or go to:What_are_the_8_groups_of_invertebrates
They can be divided into essentially nine subdividions (phyla): -Porifera -Cnidaria -Platyhelminthes -Nematoda -Annelida -Mollusca -Arthropoda -Echinoderma -Chordata (most chordates are those with backbones, so they are usually vertebrates, but some are invertebrates)
Porifera Coelenterata Platyhelminthes Nematoda Annelida Molluska Anthropeda Echinodermata
In no particular order: Chordates Echinodermata Platyhelminthes (Flatworms) Nematodes (Roundworms) Annelids (Segmented Worms) Arthropods Porifera (Sponges) Molluscs (Shells)

Flatworms.
give me some example of porifera a natural or "kitchen" or "bath" sponge
These are the eleven common Phyla but there are over 30 different classification of Invertebrates!Invertebrata Phyla includes;* Arthropoda * Nematoda * Mollusca * Annelida * Nemertea * Platyhelminthes * Rotifera * Acoelomorpha * Ctenophora * Cnidaria * Porifera Also included, but not limited, are a sub-phyla of Marine Invertebrates. Hope this helped.
Some phyla that include simple aquatic organisms are Porifera (sponges), Cnidaria (corals, jellyfish), Nematoda (roundworms), and Platyhelminthes (flatworms). These organisms often have basic body structures and are adapted to aquatic environments.

There are five main phyla in the animal kingdom: Porifera (sponges), Cnidaria (jellyfish, corals), Platyhelminthes (flatworms), Annelida (segmented worms), and Arthropoda (insects, spiders).
