Similar to vertebrates, amphioxus have a hollow spinal like chord of nerves running up and down its back. Although they split from vertebrates over 250 million years ago, they provide a lot of information about evolution.

Amphioxus
Amphioxus provides an important link towards the history of vertebrates. Also known as Lancelets, Amphioxus are strange little critters. They live in the surf of the warmer oceans. They grow to about two inches long and have a somewhat underdeveloped but defined tail and also lack fins or limbs. Their translucent bodies allows for people to see inside them. They have no skeleton in the true sense, however they do have some cartilage like material in the gills.
