Conchoderma auritum
rabbit-ear barnacle
Conchoderma auritum, commonly known as the rabbit-ear barnacle, is a pedunculate barnacle in the family Lepadidae. It is primarily known as a whale-associated barnacle, attaching to the shells of other barnacle species such as Coronula diadema on cetaceans. The species has also been documented on large pelagic fish including black marlin, representing a non-mammalian host association. It possesses distinctive tubular ear-shaped structures on the capitulum and feeds using short, thick-segmented cirri adapted for strong currents.
