Abstract

The Antarctic circumpolar ascidian Distaplia cylindrica harbors individuals of the amphipod Polycheria antarctica form acanthopoda that live in domiciles excavated by the amphipod. There was no evidence this amphipod consumed its host ascidian tissues. This burrowing association with D. cylindrica may provide an important structural or chemical refuge from prospective fish predators.
