Aplousobranch Tunicates (Simple Colonial Sea Squirts) [Aplousobranchia]

Description

Aplousobranchia are colonial tunicates that can form small, living “patches” on rocks, pilings, or coral rubble. Divers often notice them as soft, colorful blobs or thin mats that retract when disturbed and expand again as they filter-feed.
