Morphology | Morphometrics
Adults are found near shore, frequently in coastal bays at or near the surface. Often form small schools. Occasionally penetrate fresh waters (Ref. 9306). Presumably oviparous, with planktonic larvae (Ref. 36576). Eggs are attached to spawning substrate via filaments (Ref. 36576).

Estimates based on models
Preferred temperature (Ref. 115969
): 17.4 - 28.3, mean 23.4 °C (based on 64 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
