Lets do a worksheet on symmetry.

Name the 9 phylums as classification taxons.

CephalizationBilateral animals tend to have sensory

and brain in the front.

Body PlanMost have a body cavity filled with fluid.

Circulatory System

Most have a circulation system.

Circulatory SystemNo circulatory system: ex. Sponges

Open circulatory system: ex. Arthropods, mollusks

Closed system: ex. mammals

Invertebrate vs. vertebrates

Most have a circulation system.

The one thing that all invertebrates have in common is their lack of a backbone; otherwise, they're as different from one another as they are from vertebrates.

All vertebrates fall under one phylum, chordata;

invertebrates, on the other hand, include over 30 different phyla, collectively accounting for 98 to 99 percent of all known animal species.

Phylum Chordata

General Characteristics:

All chordates have a• dorsal hollow nerve tube, • a notochord, and • pharyngeal gill slits.

All vertebrates (members of a subphylum of chordata) have a backbone (spinal column) and a closed circulatory system.
