Giant Trevally

Common Name(s):
The Giant Trevally has a small oval-shaped patch of scales in the center of the larger scaleless area on the breast in front of the ventral fins, distinguishing it from the Bigeye whose breast is fully scaled. The body and head are usually very deep with a blunt snout. The lateral line is strongly curved. The straight portion is covered with 25-33. The first dorsal fin consists of 8 spines, the second of 17-21 soft rays, and anal fin of 3 spines and 15-17 soft rays. Gill rakers on the first arch total 18-23. There is no spot on the operculum such as is found in the Bigeye Trevally, nor is there a spot at the base of the pectoral fins such as appears on the Crevalle Jack.
