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. Range depth 22 (high) m 72.18 (high) ftĬommon snook are easily recognized by their elongate body, distinct sloping forehead, concave snout, and protruding lower jaw.( "Encyclopedia of Life", 2001 "Texas Parks and Wildlife Department", 2009 Froese and Pauly, 2010 Hill, 2005 Press, 2010) Most live in waters of temperatures between 25 and 31☌. As adults, common snook are generally non-migratory, but often assemble in high salinity regions in order to spawn. They commonly associate with underwater structures such as pilings, reefs, or sea grass beds, but they most often prefer mangrove-fringed estuarine habitats.
They can be found in freshwater, brackish, or marine environments at depths up to 22 m. ( "Encyclopedia of Life", 2001 "Texas Parks and Wildlife Department", 2009 Froese and Pauly, 2010 Hill, 2005 Press, 2010)Ĭommon snook are amphidromous fish, moving between fresh and salt water during their life, but not for the purpose of breeding. They are particularly abundant around coastal Florida. Common snook have been documented as far north as Pamlico Sound, North Carolina and as far south as Rio de Janeiro, Brazil.
Common snook, Centropomus undecimalis, range from the coastal mid-Atlantic regions of the United States through the Gulf of Mexico and Caribbean to parts of Central and South America.
