Nine Major Animal Phyla

The nine major animal phyla's are 

• chordates (fish, reptiles, amphibians, birds, mammals)

•  echinodermata(sea stars, sea urchins)

•  mollusks(clams, snails, oysters, octopus)

•  arthropoda(insects, spiders, crustaceans)

•  annelida(earthworm, leech, sandworm)

•  nematoda (Roundworms) 

• platyhelminthes (planaria, tapeworms)

•  coelenterates(jellyfish, hydras, corals)

•  porifera(sponges).

The types of habitat that species can be found in are freshwater, marine, and terrestrial; while in some cases the species can be found in all environments. Some species do not have digestive systems, however if they do its either complete or incomplete.I have never seen a species in phyla.
