The rare species, which typically spends its existence floating upside-down on the water's surface, lives in warm, tropical regions and feeds on venomous animals such as the Portuguese man o' war.Measuring up to 3cm in length the slug also possesses a powerful poison of its own, but while it is unlikely to do much harm to humans, picking one up with your bare hands is generally ill-advised.

Due to their rarity, finding one washed up along the shoreline is a unique and interesting event. The most recent specimen (see below) was found by Lucinda Fry on a beach in northeastern Australia.
