Dorsale stekels (totaal) : 4 - 8; Dorsale zachte stralen (totaal) : 8 - 10; Anale stekels: 1; Anale zachte stralen: 20 - 24; Wervels: 47 - 50. Branchiostegal rays: 6 (Ref. 36497).

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.

Levenscyclus en paargedrag Maturities | Voortplanting | Spawnings | Egg(s) | Fecundities | Larven

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).

Fylogenetische diversiteitsindex (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).

Trofisch niveau (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.

Weerstandsvermogen (Ref. 120179): Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (tmax=4; k >0.30; tm=1.5).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
