To quantify the abundance of nudibranchs
and other sea slugs we conducted timed counts in the low intertidal zone at 28 sites from Los Angeles County, California to Coos County, Oregon (Fig.

Adults of four species of nudibranchs
: Polycera aurantiomarginata, Polycera quadrilineata, Berghia columbina and Berghia verrucicornis were collected by hand from the same intertidal area of El Portil, located in the estuary area of the river Piedras (Huelva, SW Spain) (37[degrees]12'40"N, 7[degrees]7'50"W) (Fig.

Flabellina iodinea nudibranchs
were collected at a depth of about 4 m from Goleta Bay, California (34[degrees]24.854' N 119[degrees]49.711' W).

By contrast, structural defenses tend to develop slowly in response to parasite challenge in nudibranchs
, barnacles, bryozoans, and other aquatic invertebrates (Harvell, 1990).
The four species of nudibranchs
known to bypass a free-living larval stage and hatch as juveniles all belong to a single family, the Dendrodorididae (Goddard, 2005).
Although these data cannot be extrapolated to other groups of opistho-branchs, and some of the most conspicuously colored groups (such as chromodorid nudibranchs
) could have achieved rapid diversification because of aposematic coloration defense strategies (Johnson and Gosliner, 2012), the present paper points out the need for caution in making broad generali7ations about the biological and evolutionary role of color in opisthobranchs and other marine organisms.
He discovered 31 new species of nudibranchs

on coral reefs with his Olympus EM-1 camera in a Nauticam housing.
