Doto amyra from Oregon

From: Jeff Goddard

Hi Bill,
Here are some photos of the specimens that laid some of the egg masses on which I based my 1996 paper on lecithotrophic development in Doto amyra.

Locality:  Middle Cove, Cape Arago, Oregon, USA. Pacific coast. Intertidal. Length: 12, 7, 11 mm. June 1985 and July 1984. Rocky shore
Photographer: Jeff Goddard

The first two specimens measured 12 mm [A] and 7 [B,D]mm long respectively, and were found on the stolons of thecate hydroid Abietinaria sp. in June 1985. The third specimen was 11 mm long [C] and found at the base of the thecate hydroid Thuiaria sp. in July 1984.
As I mentioned in message [#15639], the body of Doto amyra is light colored and only rarely possesses a light scattering of dark pigment. Its ceratal cores, however, can vary from pale yellow to orange-brown or pink-brown. Doto amyra is usually found hunkered down on the stolons of thecate or athecate hydroids, including Abeitinaria, Sertularia, Aglaophenia, Garveia, and Coryne (Goddard 1996, unpublished observations).

Best wishes,
Jeff
