Now, a new genetic analysis of the hogfish reveals evidence to explain how they do it. Published in the Journal of Comparative Physiology A , the results suggest that light-sensing evolved separately in two tissues. The hogfish Lachnolaimus maximus. The hogfish is a species of wrasse native to the western Atlantic Ocean. It is present in the Caribbean and north to Bermuda and the Carolinas and extends southwards to the northern region of the Brazilian Coast. The species is found on coral reefs at feet m depth, especially sandy outer reef slopes.

Hogfish Can ‘See’ with Its Skin
This species occurs around reefs , especially preferring areas with plentiful gorgonians. This species is currently the only known member of its genus. The hogfish is characterized by a large, laterally compressed body shape. It possesses a very elongated snout, which it uses to search for crustaceans buried in the sediment. This very long "pig-like" snout and its rooting behavior give the hogfish its name. The caudal or tail fin is somewhat lunate and the pectoral fins are along the lateral sides of the body with the paired pelvic fins directly below. A prominent black spot behind the pectoral fins differentiates males from females.
