Robin Agarwal (@anudibranchmom) and I both saw this turtle in front of the boat on an all-day whale watching trip with Blue Ocean Whale Watch. Robin raised her camera, while I raised...my binoculars. The turtle took two breaths, and disappeared. We waited and searched for another fifteen minutes, but never refound it.

The photo attached here is one of Robin's. Her other photos are with her entry here: https://www.inaturalist.org/observations/14679602
