Hatchlings measure 1.4 to 1.5 mm in length. Eggs average 0.6 – 0.8 mm in diameter (0.27 mm^3 volume). The oocytes in follicles of common snook mature in a manner typical of most teleost fishes. ( "Encyclopedia of Life", 2001 "Texas Parks and Wildlife Department", 2009 Froese and Pauly, 2010 Hill, 2005 Press, 2010) The pectoral fins have 15 to 16 rays and do not reach vertical from the tip of the pelvic fins. The anal fin has 3 spines and 6 soft rays, and the second anal spine does not reach vertical from the caudal base. Common snook have 2 dorsal fins that are well-separated, each with 8 to 9 dorsal spines and 10 dorsal soft rays. Unlike in other species within the genus Centropomus, the tips of their pelvic fins do not overlap or reach the anus. The pectoral fins, pelvic fins, second dorsal fin, and the dorsal lobe of the caudal fin are all bright yellow in color, however, some specimens are considerably darker. The lateral surface tends to be silvery, and the ventral surface is generally white. Females are generally larger than males.Ĭoloration ranges from dark brown to dull gray with a yellow to green tint on the dorsal surface. Common snook range from 0.14 to 140 cm in length (average 50 cm) and can weigh as much as 23.3 kg. They are further characterized by their prominent black lateral line, which is formed by 67 to 72 pored scales, that extends into the caudal fin.
