Acanthodoris pilosa is a species of sea slugs, dorid nudibranch, shell-less marine gastropod molluscs in the family Onchidorididae.


This species was described from Norway. It has been reported from the North Atlantic Ocean on both the American and European coasts.[3][4] Specimens from Cobscook Bay, Washington County, Maine and Murles Point, County Donegal, Ireland have been sequenced for the 16S ribosomal RNA, Histone H3 and CO1 genes.[5][6] Reports of this species from Japan[7] must be considered doubtful in the light of recent molecular phylogeny results which show that at least some of the animals from the North Pacific are Acanthodoris atrogriseata.[5]


The maximum recorded body length is 15 mm.[8]


Minimum recorded depth is 0 m.[8] Maximum recorded depth is 55 m.[8]
