Diagnostic Description
provided by Fishbase
Dorsal and anal fins in adults with scales, without basal sheath of scales, and not fully depressible Interorbital space in adults strongly convex, the profile notably arched. Scales on caudal peduncle forming a graded size series with those on the bases of the midcaudal peduncle rays.
Migration
provided by Fishbase
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.
Morphology
provided by Fishbase
Dorsal spines (total): 0; Dorsal soft rays (total): 33 - 36; Analspines: 0; Analsoft rays: 27 - 30
Trophic Strategy
provided by Fishbase
Oceanic species which occurs near the surface (Ref. 2850). Feeds on cephalopods, fish and invertebrates (Ref. 4563).
Biology
