Bluestriped Grunt

The bluestriped grunt has a deep, almond-shaped body with a moderately convex dorsal profile. Its upper jaw extends to underneath the centre of the eye. The scales above the lateral line are enlarged, whereas those underneath it are arranged in a diagonal pattern. It has a continuous dorsal fin with a small to medium-sized notch in its centre. The dorsal fin contains 12 spines and 16-17 soft rays, while the anal fin contains 3 spines and 9 soft rays. The overall colour of this species' head and body is yellow broken by thin, longitudinal blue stripes. Also, a distinctively arched stripe occurs below each eye. The spiny part of the dorsal fin is yellow, the soft-rayed part of the dorsal fin and the caudal fin are dark, the anal fin is sooty yellow, and the pelvic and pectoral fins are whitish. The inside of the mouth is a vivid red. The small juveniles, below lengths of 22 mm (0.87 in) have obvious melanophores on their caudal peduncles, and as the fish grows, these grow, too, forming a dark stripe starting just behind the eye and running to the caudal peduncle. Once a length of 50 mm (2.0 in) is attained, the fish changes to the adult colouration. This species attains a maximum total length of 46 cm (18 in), although 25 cm (9.8 in) is more typical.

The bluestriped grunt is found in the western Atlantic Ocean, from South Carolina and Bermuda south along the coast of the United States to the Bahamas. They extend into the Gulf of Mexico from the Florida Keys north as far as Cedar Key and from Tuxpan in Mexico along the northern coasts of the Yucatan Peninsula to northwestern Cuba, and in all of the Caribbean Sea.
