Late embryos of Doto amyra

January 28, 2006
From: Jeff Goddard

Hi Bill,
Here is a photo of the embryos of Doto amyra close to hatching. The shells average a little over 240 microns in length. The lecithotrophic larvae can swim or crawl and are capable of metamorphosis into a juvenile within a day or two of hatching. Note the eyespots and large foot with a well developed propodium; as described by Bonar (1978, p. 187), the appearance of these structures "signal the approach of metamorphic competence" in opisthobranchs.

Locality: Montana de Oro State Park, California, USA. Pacific coast. Intertidal. Length: 240 microns (shells). May 2005. Rocky shore. Photographer: Jeff Goddard

Best wishes,
Jeff
