What is the body structure of the Acoela?
The acoels have a bilateral, creeping gastrulae with mesoderm, and their sister-group relationship with the Nemertodermatida is implied by their possession of the characteristic frontal organ. The Acoela is a small phylum of about 400 species of small, completely ciliated, mostly marine 'worms'.
