Side by Side

Bonito / Atlantic Sarda sarda

Typical: 16–24 in, 2–8 lb

Quickest tell: Straight slanted dark stripes on the back plus small visible teeth distinguish bonito from the toothless, scribble-backed, belly-spotted false albacore; bonito is striped where Spanish mackerel is spotted.

• straight, slanting dark oblique stripes along the back, angling down onto the upper sides
• stripes are linear and well-defined (not wavy scribbles)
• small but visible conical teeth in the jaws
• compact tuna-shaped body with finlets and a slim keeled tail base
• metallic blue back, bright silver sides

False Albacore Euthynnus alletteratus

Typical: 20–28 in, 5–12 lb

Quickest tell: Worm-like scribbles confined to the back plus a few dark belly spots and a smooth UNMARKED lower body separate the albie from bonito, which carries straight slanted dark stripes onto its sides and has visible teeth.

• wavy, worm-like dark green-blue scribbles on the upper back only
• 3-7 dark round spots below and behind the pectoral fin
• lower sides and belly silvery and unmarked (no stripes)
• rigid tuna body with finlets before the tail; lacks scaly corselet markings of bonito
• small, inconspicuous teeth; deeply forked tail
