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). Occur singly or in pairs (Ref. 128523). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 24.2 - 29.1, mean 28.3 °C (based on 622 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00175 - 0.01142), b=2.99 (2.77 - 3.21), 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.
Generation time: 2.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (tm=0.5-1).
