About Doto columbiana O'Donoghue, 1921
Doto columbiana is a species of nudibranch in the genus Doto. Individuals of this species typically have a cream-colored body, with grey mottled markings covering their back and sides. The body pigment can vary significantly between individuals, ranging in shade from pale grey-brown to nearly black. In more distinctly marked specimens, the dark pigment forms complete rings around the bases of the cerata. This species was first scientifically described from specimens collected by dredging, at a depth between 22 and 33 meters. The type locality is the area between Brandon Island and the head of Departure Bay, Vancouver Island, British Columbia, Canada; two additional type specimens were collected from Nanoose Bay, also on Vancouver Island. Confirmed observations of Doto columbiana have been recorded along the Pacific coast of North America, ranging from British Columbia in the north to Santa Barbara, California in the south. In its ecological habitat, Doto columbiana feeds exclusively on hydroids belonging to the genus Aglaophenia, which is part of the family Aglaopheniidae.
