Unification Aspects:

With only about 30 species, it would be easy to overlook Cephalochordata and its importance. Yet, like all taxa, lancelets serve a purpose for the whole to complement their individual purpose of survival, development and reproduction. For one, they provide a valuable scientific purpose, for they help us to understand the origins of chordates and vertebrates. They also play a key role in food chains, with sometimes thousands per square meter of sand. Furthermore, they also serve as a commercial food for humans and domesticated animals, and help to contribute to the diversity of form and behavior that makes nature so fascinating to people.
