Yes, there is a fish in each of these photos! The endemic Strasburg’s Blenny is less than two inches long and is easily overlooked. It tends to move about in short, sharp bursts, blends in well when it settles, and is almost undetectable when it backs into its hole. That’s where the blenny is in the top photo.
In the second photo, it’s lying out in the open, but blending in rather well. Can you spot it?
