A big nurse shark gets some rest while wedged into a crevice connected to one of the many 'potholes' formed in the limestone on the reef. With it's tail hanging out the back end, and it's head peeking out the front, it wasn't very well hidden, but when you get to be this big, I guess you don't have to worry about hiding so much anymore, but it's nice to get out of the current.Lauderdale by the Sea, Broward County, Florida, U.S.A.SeaLife DC1400Explore Jul 19, 2014 #91
