Biology     Glossary (e.g. epibenthic)

Inhabits gravel or sand bottoms around shallow reefs (Ref. 559); muddy estuaries and near mangroves, tolerating brackish waters (Ref. 48635). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00427 (0.00168 - 0.01086), 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. 69278):  High, minimum population doubling time less than 15 months (tm=0.5-1).
Vulnerability (Ref. 59153):  Low vulnerability (18 of 100) .
