Description

The Snook (Centropomus undecimalis), also known as “snook,” is an iconic mangrove fish that reaches 80–140 cm as an adult. It is easily recognizable by its elongated, fusiform body, which ranges from silvery gray to brown-green depending on its environment. It has a very prominent black lateral line and fins that tend toward yellow. Its large mouth is filled with numerous sharp teeth. The species has a lifespan of about seven years. Generally, males are slightly longer than females, though this difference is difficult to distinguish visually.

The Snook is a carnivorous fish that feeds primarily on other fish, crustaceans, cephalopods, and various marine organisms. It is an expert ambush predator. When hunting alone, it remains motionless for long periods, blending into its surroundings before striking its prey. In groups, Snook cooperate to encircle and destabilize schools of prey before attacking. It is also known for its impressive swimming speed.

Habitat

Snook prefer water temperatures between 25 and 31 °C, with moderate to slow currents, and at depths of 1–22 m. They are primarily found in mangroves, coastal saltwater areas, estuaries, and lagoons.

In terms of distribution, Snook are found along the coasts of the Gulf of Mexico and Florida, throughout the Caribbean Sea, in the Atlantic north of Brazil, and in the southwestern tropical Atlantic. This predatory fish is also known for seasonal migrations and its ability to move between freshwater and saltwater at different stages of its life.

Threats

The main threat to Snook is sport fishing. This species is highly prized by recreational anglers for its fighting ability and culinary value. It is listed on the IUCN Red List as a species of Least Concern.
