Kammal Thryssa

Belly with 23 to 25 (rarely 24 or 26) keeled scutes from isthmus to anus. Maxilla moderate, reaching just to gill opening or a little beyond in large fishes; first supra-maxilla about half of second. A diffuse dark `saddle' on nape.

Oceanodromous. Migrating within oceans typically between spawning and different feeding areas, as tunas do. Migrations should be cyclical and predictable and cover more than 100 km.

Dorsal spines (total): 0; Analspines: 0; Analsoft rays: 30 - 33

Observed transient in the intertidal zone (Ref.49162). Presumably schooling and occurring mostly inshore (Ref. 55455). Juveniles and/or adults are found in mangrove inlets, intertidal mud flats and subtidal edge of mud flats (Ref. 121464). Feeds on plankton (Ref. 58477). Plankton feeder and carnivorous predator (Ref. 117095).

Presumably schooling and occurring mostly inshore. More data needed based on correct identifications.
