Widespread Indo-West Pacific species
southern Yorke Peninsula, South Australia, February 1985. 3mm long alive. PHOTO: Bill Rudman.
This is one of the smallest species of Philine, and one of the few which is not a translucent white colour. The resemblance of its characteristic colour pattern of black patches on a white background, to the colours of the killer whale Orca, are the reason for its scientific name.
