In some places there can be up to five thousand lancelets per square meter of sand! The term "amphioxus" is still used as a common name along with "lancelet", especially in the English language. Here we analyze genome sequences of three amphioxus species, and uncover their extraordinary conservation with vertebrates in chromosome composition and conformation. Amphioxus was first discovered in Europe as a lancelet. Members are structurally similar to vertebrates in having a notochord, gills, digestive tract, and nerve cord, but they lack paired fins, vertebrae, ribs, or a skull for example, Branchiostoma lanceolatum.
