生物学特性     字汇 (例如 epibenthic)

Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 3.5-4.8 cm long and 2.5-3.0 cm wide (Ref. 41249, 41298).

卵生的。 明显的成对出现。 幼鱼可能倾向跟随大的个体, 例如他们的母亲.(参考文献 205) 卵为长方形鞘囊具有僵硬的触角沈积在沙滩或泥滩的角落.(参考文献 205) 卵鞘是 3.5-4.8 公分长与 2.5-3.0 公分宽的.(参考文献 41249,41298)

Estimates based on models

Preferred temperature (Ref. 115969): 16 - 23.2, mean 21.8 (based on 14 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00302 (0.00141 - 0.00645), b=3.24 (3.07 - 3.41), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.9   ±0.6 se; based on size and trophs of closest relatives
回复力 (Ref. 120179):  低的, 最小族群倍增时间4.5 - 14 年 (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (27 of 100).
