Cottonmouth jack
The cottonmouth jack, ''Uraspis secunda'', is a gamefish in the family ''Carangidae''.

It is also known as the cottonmouth trevally.

Adult cottonmouth jack are usually dark in color, while juveniles are pale with six or seven brown, vertical bars along their sides.〔Smith-Vaniz, W.F., 1986. Carangidae. p. 638-661. In M.M. Smith and P.C. Heemstra (eds.) Smiths' sea fishes.

The anal fin has only three spines and nineteen to twenty three soft rays.〔
