Biology     Glossary (e.g. epibenthic)

Inhabits subtidal lagoon and seaward reefs, usually among algae or seagrasses (Ref. 9710). Most are seen on sand and mud areas, prone to currents; usually soft bottom to about 25 m (Ref. 48635). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).

Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.00035 (0.00015 - 0.00078), b=3.19 (3.00 - 3.38), 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) 		Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability
(Ref. 59153) 		Low to moderate vulnerability (31 of 100). 🛈
