Painted greenling fish and Hermissenda crassicornis nudibranch.

Photo of the Week: Painted Greenling (and a Bonus Hermissenda Nudibranch)

I dropped onto the Ruby E wreck and fired off this test shot in the general direction of a painted greenling, just to make sure everything was working correctly. I didn’t give it another thought.

… That is, until I got home and saw the tiny stowaway in the top of the frame.

Those who have been following this blog for any length of time will recall that finding tiny surprise creatures in a photo is one of my favorite things in the whole world.

It just raises so many questions. Do painted greenlings eat nudibranchs? Is this Hermissenda crassicornis about to become fish food? Is it just a happy coincidence that the fish and the slug are occupying the same few square inches of the 166-foot wreck?

I may never know.

All I know is that’s one seriously tiny nudibranch.
