Actinopterygii (ray-finned fishes) > Perciformes
(Perch-likes) > Sphyraenidae
Etymology: Sphyraena: Greek, sphyraina, -es = the name of a fish (Ref. 45335).
Environment / Climate / Range
Marine; brackish; reef-associated; depth range 1 - 100 m (Ref. 6949), usually 3 - 30 m (Ref. 40849). Subtropical; 42°N - 35°S, 180°W - 180°E (Ref. 55300)
Length at first maturity / Size / Weight / Age
Maturity: Lm 66.0, range 58 - ? cm
Max length : 200 cm TL male/unsexed; (Ref. 7251); common length : 140 cm TL male/unsexed; (Ref. 3692); max. published weight: 50.0 kg (Ref. 6949)
soft rays: 10. Distinguished by the double emarginate tail fin with pale tips on each lobe, and (usually) the presence of a few scattered black blotches on the lower sides (Ref. 1602). Top of head between eyes flat or concave; mouth large (Ref. 26938).
Indo-Pacific: Red Sea and east coast of Africa to Hawaii and the Marquesan and Tuamoto islands. Western Atlantic: Massachusetts (USA), Bermuda, and throughout the Caribbean Sea to Brazil (Ref. 9626). Eastern Atlantic: Sierra Leone, Côte d'Ivoire, Togo, Nigeria, Senegal (Ref. 6949), Mauritania (Ref. 5377), St. Paul's Rocks (Ref. 13121), and São Tomé Island (Ref. 34088).
Found predominantly at or near the surface (Ref. 6949, 48637). Juvenile occurs among mangroves, estuaries and shallow sheltered inner reef areas; adult occurs in a wide range of habitats from murky inner harbors to open seas. Diurnal and solitary, but can also be found in small aggregations. Feeds on fishes, cephalopods and sometimes on shrimps (Ref. 9626, 48637). Sold fresh. Utilized also dried or salted (Ref. 9987). Although this species is ciguatoxic elsewhere throughout its range, it has not been reported to be poisonous in the eastern Atlantic (Ref. 6949, 48637). Rarely attacks humans, usually with one quick, fierce strike, which, although serious, is rarely fatal. The world's record on hook and line is a 5.5-ft. fish taken in the Bahamas that weighed 103 lbs. (Ref. 13442).

Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00749 - 0.01162), b=2.92 (2.87 - 2.97), based on LWR estimates for this species (Ref. 93245
Trophic Level (Ref. 69278
): 4.5 ±0.8 se; Based on diet studies.
Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (K=0.09-0.11; tm=2-4).
Vulnerability (Ref. 59153
): Very high vulnerability (79 of 100) .
