Lancelet (Branchiostoma sp.). The lancelet (or Amphioxus) is a primitive relative of the fish. It lacks a true backbone,but does have a notochord,a supporting rod that is considered to be the evolutionary forerunner to a full backbone. It lives in sediment with its mouth (upper left) protruding,and it uses fine tentacles to waft food into its mouth. The lancelet can reach a length of up to two centimetres | |
