Doto amyra form A of Goddard (1996)

From: Jeff Goddard

Hi Bill,

Here are two photos [A, B ] of some of the specimens I referred to as Doto form A in my 1996 paper on the development of Doto amyra. These specimens were 7 mm long and were collected from small thecate hydroids under cobbles at the mouth of Drake's Estero, Point Reyes National Seashore in northern California in. Their egg masses produced small planktotrophic larvae with shells averaging 123 microns in length. I have also observed this form and its egg masses under intertidal cobbles at Rincon Point in Santa Barbara County.

Locality:  Drake's Estero, Point Reyes National Seashore, California, USA
Pacific coast. Interidal. Length: 7 mm. 24 April 1984. Rocky shore. Photographer: Jeff Goddard

I have also included an image [Photo C] of one of a specimen (4.5 mm long) of Doto and its egg masses in a photograph taken by Hans Bertsch at 60' off of La Jolla, California. Because I didn't examine this specimen directly, I referred conservatively to it in my 1996 paper as a 4th form of Doto that would be identified as Doto amyra as currently understood. The external similarities of this specimen to the specimens of form A from Drake's Estero are obvious, and I consider them to be the same.

These specimens appear to be the same as the specimen referred to as Doto amyra in Behrens (1991), as well as the specimens pictured in Sean Kearney's message [#12493 ].
