Etymology: Scomberomorus: Latin, scomber = mackerel + Greek, moros = silly, stupid (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; pelagic-neritic; oceanodromous (Ref. 51243); depth range 15 - ? m (Ref. 9987). Subtropical; 32°N - 26°N, 115°W - 108°W
Eastern Central Pacific: endemic to the northern Gulf of California.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 77.0 cm FL male/unsexed; (Ref. 33255); max. published weight: 3.6 kg (Ref. 168)
(total): 15 - 18;
soft rays: 19 - 23;
Vertebrae: 46 - 48. Interpelvic process small and bifid. Swim bladder absent. Lateral line gradually curving down toward caudal peduncle. Intestine with 2 folds and 3 limbs. Males with no streaks or spots while females have two alternate series of brown spots on sides. Body entire covered with small scales, no anterior corselet.
It is now extinct outside the Gulf of California. Supports a commercial net fishery close inshore, in estuaries and coastal marshes (Ref. 9987). Its biology is almost completely unknown. This fishery operates on a relict of the original population.

Estimates based on models
Preferred temperature (Ref. 123201
): 19.7 - 23.6, mean 22.2 °C (based on 14 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00383 - 0.01808), b=3.03 (2.86 - 3.20), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.3 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Moderate to high vulnerability (54 of 100).
