Found frequently in coastal waters to 10 m depth, mainly in shallow estuaries. Capable of traveling long distances, occasionally leaps out of the water. Swims in midwater. Cruises slowly over the bottom, rooting out bivalves with its beak and wings when feeding (Ref. 7251). Ovoviviparous (Ref. 50449).

Estimates based on models

Preferred temperature (Ref. 115969): 14.2 - 28.1, mean 24.2 (based on 594 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00123 - 0.01235), b=3.08 (2.82 - 3.34), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

营养阶层 (Ref. 69278): 3.4 ±0.0 se; based on diet studies.

回复力 (Ref. 120179): 非常低的, 最小族群倍增时间超过14 年 (Fec=4-8).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (83 of 100).
