Ch. 4 Study session

There are six classes of this phylum Echinodermata: Asteroidea, Ophiuroidea, Echinoidea, Crinoidea, Holothuroidea, and Concentricycloidea.

This phylum comes in 3 basic shapes: branching, vase-like and encrusting.

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.

Class Insecta of this phylum __________ & subphylum Hexapoda (having six legs) is the most diverse of all the arthropod groups.

Cephalopoda ("head foot”) is part of this phylum & perhaps the most intelligent members of all the invertebrate phyla.

Members of this phylum come in two variations: the sessile polyp and the floating medusa.

Snails, scallops, and octopuses are all members of this phylum?

What Phylum have a segmented body giving them a ringed appearance?

Most members of this group are extremely dorsoventrally flattened (squashed flat), giving the phylum the name?

The sea stars, sand dollars and sea urchins all belong to this phylum

Sponges part of this phylum are the least complex of all animals. They are asymmetrical organisms that lack tissues, organs, nerves and muscles.

This phylum generates a current that brings water inward through incurrent pores and outward through the excurrent opening called the osculum.

Members of this phylum are constructed with a classical coelomate body plan, a tubular-shaped gut running through the middle of a coelom.

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.

Members of this phylum are capable of locomotion using true muscle tissue and are the most primitive organisms with a central nervous system.

Lobster, shrimp, barnacles, copepods, insects and spiders all belong to this phylum.

Members of what phylum include 10,000 species of radially symmetric animals such as jellyfish, coral, and sea anemones?

Members of this phylum are completely covered by a cuticle, an exoskeleton made up of layers of protein and chitin.
