Opalescent Nudibranch

Hermissenda crassicornis


The white stripes shine with an opalescent blue tinge, hence the name. I have been hoping to see one of these for a long time, but I didn't realize they were in Alaska so I was taken by surprise! It was also larger than I was expecting, probably close to 3 inches (~7.5 cm) long


Found on the side of a concrete dock in a harbor

Thanks Jim and Christine! Jim, the dock was halfway sunken and only floating because it was chained to the main docks, so many animals were exposed that I think are normally a little deeper and more covered. It was a great opportunity to photograph some animals that are normally more awkward to photograph.

Machi...great photography and spotting. Usually you have to go deeper to find these guys.
