Biology     Glossary (e.g. epibenthic)

Found in shallow water on sandy bottoms, sometimes adjacent to reefs (Ref. 12951). Found buried in the sand during the day (Ref. 12951). Moves into shallow bays at night to feed; prefers polychaete worms, but may take sea squirts (Ref. 12951).

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=0.01072 (0.00301 - 0.03809), b=2.79 (2.53 - 3.05), based on LWR estimates for this (Sub)Family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.0   ±0.18 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (32 of 100) .
Price category (Ref. 80766):   Unknown.
