In this lab, you'll examine several different specimens of Branchiostoma, which is also called Amphioxus.Although the name Amphioxus is commonly used, Branchiostoma is the correct scientific name for this genus, so I'll use that name on this page. This organism also goes by the common name "lancelet," supposedly because it resembles a small lance.
