A bracket-shaped marking that is usually white or light gray behind the eye, is a sure sign that the species is a Pygmy Sperm Whale. Called a “false gill,” this comma-shaped coloring is not a gill, just a skin coloration that makes many first-time spectators think the whale is a shark. Researchers are still unclear about the purpose of the false gill.
