Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 15 - 16.

In Zostera seagrass beds; also in estuaries. Length type refers to height (= TL - head length). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Minimum depth reported taken from Ref. 128812.

Estimates based on models

Preferred temperature (Ref. 115969): 15.9 - 29.2, mean 28.5 (based on 1779 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00447 (0.00177 - 0.01127), b=3.00 (2.78 - 3.22), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.50 se; based on food items.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (tm=0.5-1).

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