Bonnetmouth

The bonnetmouth has a cigar-shaped body and can grow up to 13 cm (5.1 in) in total length. Bonnetmouths are generally yellowish-gray, with some blue coloration on the front and silvery-white on the sides. Adults have four brown stripes on the upper halves of their bodies (one mid-dorsal), while juveniles have only three stripes. These stripes are usually more evident near the front and become more faded near the tail.

Found only in the western Atlantic Ocean, bonnetmouths can be seen from southern Florida and the Bahamas to northern South America. They can be captured most often near the Florida Keys, US Virgin Islands, and the Bahamas. The type specimens were both collected off the Bahamas' Cat Island. They are generally associated with reefs and can be found over coral heads in small groups. Bonnetmouths can be found at depths from 3–90 m (10–300 ft), but mainly occur in schools at about 64 m (210 ft). It feeds on invertebrates and small fishes.
