The Lookdown fish was first described in 1758 by Carolus Linnaeus in the 10th edition of his book Systema Naturae. The Lookdown is a thin fish that is silvery on both sides, although young fish have several faint vertical bars on each side that fade as the fish matures. The Lookdown fish of the western Atlantic are found from Canada and Maine, south to Uruguay, including Bermuda and the Gulf of Mexico. I took this photo at the Tennessee Aquariums, Ocean Journey exhibit.
