Species description | |
These transitional animals have characteristics common to both vertebrates and invertebrates. The amphioxus resembles a simple fish with its stiff dorsal fin (notochord) and its system of gill slits used to feed on small particles. It has no heart and the barest indication of a brain. Like invertebrates, the amphioxus have numerous paired excretory organs and of course, no vertebrae. |
