Dorsal spines (total): 12-14; Dorsal soft rays (total): 13-15; Anal spines: 0-0; Anal soft rays: 13-16; Vertebrae: 39-39. A very large species, deepest near the middle of the first dorsal fin base. The second dorsal fin higher than the first; the pectoral fins are very short, less than 80% of head length. Swim bladder present. Lower sides and belly silvery white with colorless transverse lines alternated with rows of colorless dots. The first dorsal fin is yellow or bluish; the second reddish-brown; the anal fin and finlets dusky yellow and edged with black; the median caudal keel is black in adults. May be confused with several other tunas, these are typically much smaller and easily distinguished by specific patterns of stripes, bands or dots. |
| Oceanic but seasonally coming close to shore. They school by size, sometimes together with albacore, yellowfin, bigeye, skipjack etc. Visual predators (Ref. 88866) preying on small schooling fishes (anchovies, sauries, hakes) or on squids and red crabs. Live up to 40 years in the western Atlantic (Ref. 88822). Weight up to 900 kg (Ref. 88823). Eggs and larvae are pelagic (Ref. 6769). Juvenile growth is rapid (about 30 cm / year) but slower than in other tuna
and billfish species (Ref. 88867). Adult growth is considerably slower, with about 10 years needed to reach two thirds of maximum length. Become rare because of massive overfishing (Ref. 35388). |
