Velvet belly lanternshark with Anelasma. This barnacle reaches a length of approximately 25 mm. Unlike most barnacles, it has no shell; the outermost integument is its tough, purplish-black mantle, without any calcareous plates. The body protrudes from the skin of its host and is usually encountered in pairs.
