Is Branchiostoma a Deuterostome?

Is a jellyfish a Protostome or deuterostome?
Are jellyfish deuterostomes? The majority of animals more complex than jellyfish and other Cnidarians are split into two groups, the protostomes and deuterostomes. Chordates (which include all the vertebrates) are deuterostomes. It seems likely that the 555 million year old Kimberella was a member of the protostomes.

Is Branchiostoma the same as Lancelet?
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. Recognize and name the anatomical features described on this page.
