Dorsal spines (total): 4 - 8; Dorsal soft rays (total): 8 - 10; Anal spines: 1; Anal soft rays: 20 - 24; Vertebrae: 47 - 50. Branchiostegal rays: 6 (Ref. 36497).

Biology     Glossary (e.g. epibenthic)

Adults inhabit inshore waters, usually at or near surface along open coast and in bays (Ref. 36497). Oviparous, with planktonic primarily neustonic larvae (Ref. 36497). Eggs are deposited in the sand at night by the female parent (Ref. 58332) just below the high spring tide line (Ref. 36497). Minimum depth reported taken from Ref. 57178.

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

Demersal spawners. Spawn at night on sand beaches at high tides in the spring and summer. Eggs are buried in moist sand by the female parent (Ref. 58332) and hatch about 15 days later during the next series of high tides (Ref. 2850). Females spawn 4 to 8 times during a season (Ref. 4563).

Estimates based on models

Preferred temperature (Ref. 123201): 15 - 23.2, mean 21 °C (based on 103 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00603 (0.00275 - 0.01321), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.9   ±0.4 se; based on size and trophs of closest relatives
Generation time: 3.3 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (tmax=4; k >0.30; tm=1.5).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Price category (Ref. 80766):   Unknown.
