Menhaden have a deep body, sharp-edged belly, large head, and tooth-edged scales. Adults are about 15 in. (38 cm) long and weigh 1 lb (0.5 kg) or less. Dense schools of menhaden range from Canada to South America. When feeding, they swim with mouth agape and gill openings widespread to strain out plankton.
