This phylum comes in 3 basic shapes: branching, vase-like and encrusting.
Porifera
Members of what phylum include 10,000 species of radially symmetric animals such as jellyfish, coral, and sea anemones?
Cnidaria
Most members of this group are extremely dorsoventrally flattened (squashed flat), giving the phylum the name?
platyhelminthes, which means "flat worms"
What Phylum have a segmented body giving them a ringed appearance?
Annelida
Snails, scallops, and octopuses are all members of this phylum?
Molluska
Lobster, shrimp, barnacles, copepods, insects and spiders all belong to this phylum.
Arthropoda
The sea stars, sand dollars and sea urchins all belong to this phylum
Echinodermata ("spiny skin”)
Individuals of what phylum can be found in most aquatic habitats, in wet soil, in the moist tissue of plants, and in the body fluids and tissues of animals.
Nematoda "roundworms"
This phylum generates a current that brings water inward through incurrent pores and outward through the excurrent opening called the osculum.
Porifera
Members of this phylum come in two variations: the sessile polyp and the floating medusa.
Cnidarians
Members of this phylum are capable of locomotion using true muscle tissue and are the most primitive organisms with a central nervous system.
Platyhelminthes "flatworms"
Members of this phylum are constructed with a classical coelomate body plan, a tubular-shaped gut running through the middle of a coelom.
Annelida
Chitons of this phylum, have a very distinctive shell made up of a series of eight overlapping and articulating plates covering the dorsal, or back, surface.
Molluska
Members of this phylum are completely covered by a cuticle, an exoskeleton made up of layers of protein and chitin.
Arthropoda
There are six classes of this phylum Echinodermata: Asteroidea, Ophiuroidea, Echinoidea, Crinoidea, Holothuroidea, and Concentricycloidea.
Echinodermata
Cephalopoda ("head foot”) is part of this phylum & perhaps the most intelligent members of all the invertebrate phyla.
