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.

This octopus does not have a shell either, but it is still a mollusk.

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.

Class Amphibia includes semi-aquaticanimals with moist skin. They must return to the water to breed.
