Biology     Glossary (e.g. epibenthic)

Lives over sandy bottoms with gravel and isolated reefs. Often caught in the open sea as a by-catch of trawlers fishing for prawns and shrimps. Each individual functions first as a female but later changes to a male (Ref. 47122).

Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.00955 (0.00437 - 0.02085), b=3.10 (2.91 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		3.5   ±0.5 se; based on size and trophs of closest relatives
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 (34 of 100). 🛈
Price category
(Ref. 80766) 		Very high.
