Knoutsodonta jannae is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusc in the family Onchidorididae.[2] It was frequently mis-identified as Onchidoris muricata.[1] K. jannae is the type species of the genus Knoutsodonta.[3]

Distribution

This species was described from Tyee Point, Copper Cove, British Columbia, Canada, (49°22′8″N 123°16′5″W). It is currently known from Prince William Sound, Alaska south to Lion Rock San Luis Obispo County, California.[4][1][5] A specimen from Pillar Point, San Mateo County, California was sequenced for the genes 16S, partial 18S, partial 28S, Histone H3, and the DNA barcoding Folmer region of Cox1 and a specimen from Prince William Sound, Alaska was sequenced for 16S and H3 in an investigation which established the genus Knoutsodonta.[3]

Diet

In British Columbia Knoutsodonta jannae is found feeding on Membranipora serrilamella and Membranipora membranacea on blades of large brown algae.[1] In California orange coloured specimens recorded as Adalaria sp. were found feeding intertidally on the orange bryozoan Lyrula hippocrepsis.[6] Lemon yellow specimens were reported to feed on Reginella mucronata.[1][7]
