Actinopterygii (ray-finned fishes) > Perciformes
(Perch-likes) > Sphyraenidae
Etymology: Sphyraena: Greek, sphyraina, -es = the name of a fish (Ref. 45335). More on author: Girard.
Environment: milieu / climate zone / depth range / distribution range
Marine; pelagic-neritic; oceanodromous (Ref. 51243); depth range 0 - 18 m (Ref. 2850). Temperate; 58°N - 24°N, 155°W - 111°W
Eastern Pacific: Alaska to Magdalena Bay, Baja California. Not common north of Point Conception (Ref. 11484).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 145 cm FL male/unsexed; (Ref. 40637); max. published weight: 12.0 kg (Ref. 40637); max. reported age: 12 years (Ref. 56049)
Usually near shore or near the surface (Ref. 2850). Often in small schools (Ref. 2850). Young enter bays (Ref. 2850). Feed mainly on other fishes (Ref. 2850). Pelagic spawners (Ref. 56049). Migrate south from the California coast during autumn, but may remain in front of the Mexican coast throughout the year (Ref. 9345). Utilized fresh, dried or salted and frozen; eaten broiled and baked (Ref. 9988). Considered as potentially dangerous due to its large, sharp teeth and aggressive disposition, though there are no reports of attacks (Ref. 9988).
Pelagic spawner (Ref. 56049).

Estimates based on models
Preferred temperature (Ref. 115969
): 8.9 - 23.1, mean 12.4 °C (based on 212 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00336 - 0.01560), b=2.92 (2.75 - 3.09), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.5 ±0.80 se; based on food items.
Generation time: 7.9 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.14; tm=2-3; tmax=12; Fec=42,000).
Vulnerability (Ref. 59153
): High to very high vulnerability (69 of 100) .
