Doto kya Marcus, 1961
You know, I have always hated Doto's. Several of our colleagues and grad students have attempted to clarify distinctions between species, but all eventually throw in the towel. Today's good news is that Tracy's specimen, shown above, fits Marcus's original description perfectly. The rhinophoral sheaths have distally expanding fluted margins, with white flecks. Both black and white specks are scattered over the white-yellow body. Some form irregular blotches, along the sides of the body, as seen here. The ceratal cores vary widely in color depending on the food source, ranging from white to brown. Cerata bear four to five rings of oval tubercles. You can find this species on the hydroids, Obelia, Plummularia, Abietinaria, Sarsia and Eudendrum.
The species ranges from Vancouver Island, British Columbia to San Diego, where Tracy's photo was taken.
Named, with one of several Aleut Indian words for "seal" - kya, specimens may reach 10 mm in length.
