Postcard from the Reef – Fellows Nudibranch

I have seen and photographed these fellows a few times. Endemic to the Central Pacific, the species is commonly seen in dives on the west coast of Hawai’i. The surprise this time was what I found nearby. A flash of bright white is quickly spotted in the beam of my light as I explore the cave. Two spots appeared on the cave roof. The first is the nudibranch, quickly recognized as a Fellows Nudibranch.

I take a couple photos, even though I have seen this species often enough before. I do not immediately notice that the second spot, somewhat hidden in a crevice, is not the same. Upon another look it turns out to be an egg mass, bright white like the slug that laid it. A neat spiral of white eggs against the algae covered rock.
