The Peculiar Doriopsilla (Doriopsilla peculiaris) was first described by Abraham in 1877 from a specimen collected in southern Australia. It is known to occur in the waters of southern Australia and it has been recorded in Western Australia, South Australia, Tasmania, Victoria and New South Wales). This species is yellow to pale pink in colour and generally has small white patches covering the upper surface. The rhinophores and gills are generally a little bit dark in colour than the mantle. This species is known to feed on sponges and it is generally only seen at night. Further investigations into this species are required as there are many similar looking species that may actually be the one species.
The Peculiar Doriopsilla (Doriopsilla peculiaris) grows to a maximum length of approximately 5cm.
