Acoela [Acoela]

Description

The Acoela are a small group of simple flatworms, primarily marine, characterized by lacking a digestive cavity. They are bilaterally symmetrical and have a simple body plan with a mouth but no anus. Acoels are important for studies on the evolution of bilateral symmetry and the digestive system in animals. They inhabit various marine environments, from intertidal zones to deep sea, often found under rocks or buried in sediments.
