Short description
Morphology | Morphometrics
Dorsal
spines
(total): 3;
Dorsal
soft rays
(total): 23-26;
Anal
soft rays: 20 - 22;
Vertebrae: 32 - 35. Narrow interorbital distance (29-65 thousandths of SL), usually less than the diameter of the orbit (60-104 thousandths of SL), versus usually equal to or wider than the orbit diameter in other Opsanus species. Similar to O. phobetron, both usually have the posterior part of lower half of the mouth darkly pigmented in specimens over 7 cm SL. Upper lateral-line papillae 26, lower 23. Pectoral fin glands 12, starting between uppermost 2 pectoral fin-rays (Ref. 41041).

Estimates based on models
Preferred temperature (Ref.
123201): 26.6 - 28.3, mean 27.5 °C (based on 256 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.6 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.
