| Phylum Chordata | ||
|
Chordates have three features in common. They
have a nerve chord (expanded into the brain on the upper side of the
body), notochord (supporting structure) and gill slits (connect the
throat with the outside of the body). They may have these features at
SOME stage in their lifecycle, but not necessarily every stage. Most
chordates are vertebrates (they have a backbone). Some chordates don't,
including the Class Ascidiacea (Ascideans, sea squirts, tunicates).
The following Chordates are found at the Marine Discovery Centre: Class Ascidiacea (Ascideans, sea squirts, tunicates) Class Chondrichthyes (Cartilaginous fishes - sharks, rays, skates) |
