The cottonmouth jack (Uraspis secunda) is a gamefish in the familyCarangidae. It was first described in 1860 by CubanzoologistFelipe Poey in his two-volume work Historia Natural de la Isla de Cuba, or "Natural History of the Island of Cuba". It is also known as the cottonmouth trevally.
Description
Adult cottonmouth jack are usually dark in color, while juveniles are pale with six or seven brown, vertical bars along their sides.[3] They are named "cottonmouth" because they are distinguished from other members of their family by their bleach-white mouth and tongue.[4] The cottonmouth jack's dorsal fin has a total of nine spines and twenty seven to thirty two soft rays. The anal fin has only three spines and nineteen to twenty three soft rays.[3]
The longest known cottonmouth jack measured 50 cm [5] and the greatest published weight was 2.04 kg.[6]
Cottonmouth jack usually swim throughout the water column but they are occasionally seen feeding on the bottom near islands. They do not live in large numbers and are usually seen as individuals or in small schools.[12]
