A newly discovered species

How’s that for an Intelligently Designed squirt?

Although a sea squirt may appear to be a worm, or other invertebrate, it actually has a spinal chord. So its basic physical structure is that of chordate animals, like birds and humans. However, unlike the other chordates the sea squirt does not have a backbone. Sea squirts have been likened to the Venus Fly Trap plant because they catch their prey in a similar manner and are carnivorous.

So, a spinal cord but no vertbrae for a backbone.

Does that mean it is "irexpandable complexity" to evolve one at a later time?
