Description

My Marine Biology students and I observed about 50 medium to large-sized specimens and their egg masses in shallow tidepools on intertidal sand flats. The largest shell we found measured 58 mm in length. Eliza Merrall, a student in the class, took these two images.

Found 18 large individuals in the intertidal on this date. As seen in the 2nd image, two were next to their egg strings underneath a ledge. 3rd image shows a roughly 1 mm length of egg string, with tens of embryos packed into each capsule, and the 4th image is of a veliger that hatched on Oct 17 from the same egg string as in the previous images.

Found as is. Looks like it's about to encounter the hydroid polyp at lower right.

Hermissenda opalescens was common at this site on this morning, but with some of the cerata on the individual pictured appear to have partial blue-white stripes, suggesting it may have been either H. crassicornis or a hybrid.

About 10 mm long. We found 11 individuals of this species on this morning, the most we've seen at any one time. Because we have not previously sampled this site at night, or at this time of year, we can't rule out any of the following for this species: that they tend to be nocturnal, occur more at this time of year, were present in greater numbers owing to the warm ocean of the past few years, or some combination of these. The 2nd image shows a specimen as found, before dawn, crawling out in the open on red algae.

Description

I counted 33 of these in a couple hours of searching for nudibranchs at low tide; most of the D. fragilis were out in the open, crawling on algae in tide pools, and it was the most abundant nudibranch on this morning. Interestingly, in my previous couple of trips to this site (around 2010), we have not found this species before.

The last 3 images were taken two days later at the same site.
