Together We Can
The animal kingdom can be dividedinto smaller groups. Each group is called a phylum.
Animal Kingdom
The major phyla of the animal kingdom are Porifera, Cnidaria, Platyhelminthes, Aschelminthes, Mollusca, Annelida, Arthropoda, Echinodermata and Chordata.
The latest minor phyla discovered are Phylum Cycliophora, (1983), Loricefera (1995), and Microagnthozoa (2000).
PHYLUM PORIFERASponges

SpongesSponges are sessile animals (they spend their lives attached to rocks)
Water enters the small pores of a sponge, travels through canals, and exits through a large hole at the top of the sponge.

PHYLUM CNIDARIAJellyfish, sea anemones, corals
Sea anemones

Members of this phylum have tentacleswith stinging cells.
Cnidarians can have one of two body shapes: an umbrella-shaped medusa form, like the jellyfish on the left, or a vase-shaped polyp form, like the sea anemone on the right.
Freshwater Hydra Comb Jellies
Coral reefs contain many members of Phylum Cnidaria.

PHYLUM PLATYHELMINTHESFlatworms
The worms in this phylum are all very thin and flat, like this parasitic liver fluke.
All flatworms, including this planarian, have bilateral symmetry.
Flatworms are the first animals to have a head. Note the hooks and suckers on the head of this tapeworm.

PHYLUM NEMATODARoundworms
Nematodes are not segmented; their body surfaces appear smooth.
Many nematodes are parasites, such as this pork worm named Trichinella.
Nematodes have a complete digestive tract, with a mouth at one end where food enters, and an opening at the other end where wastes exit.

PHYLUM MOLLUSCAClams, snails, squid, octopus
Most mollusks have a hard shellcovering their soft bodies.
Clams have a wedge-shaped muscular foot used for locomotion.
Mollusks breathe by means of gills. Not all mollusks have shells. This squid does not.

PHYLUM ANNELIDAEarthworms, sandworms, leeches
EarthwormLeeches
Annelids have bodies that are segmented (divided into sections).
Annelids have a circulatory system to pump blood. This earthworm has 5 hearts!
Annelid worms have a body cavity called a coelom which provides room for organ development.

PHYLUM ARTHROPODACrayfish, lobsters, crabs, insects, spiders
All arthropods, including this tick,have jointed legs.
Arthropods have a crunchy shell called an exoskeleton.
Arthropods have very well-developed sense organs.

PHYLUM ECHINODERMATASea star, sand dollars, sea urchins
Echinoderms have spiny (prickly) skin.
Adult echinoderms have radial symmetry.
The bottom of this sea star is covered with tube feet for locomotion.

PHYLUM CHORDATAFish, amphibians, reptiles, birds, mammals
Members of Phylum Chordata have a backbone (they are vertebrates).
Phylum Chordata can be subdivided into 7 classes:
AGNATHACHONDRICHTHYES
OSTEICHTHYESAMPHIBIAREPTILIA
AVESMAMMALIA
Class Agnatha includes jawless fish such as lampreys. They are parasites on other fish.
