Lives in burrows excavated in clean sand, often in association with the sandprawn Callianassa kraussi (Ref. 52193). Restricted to sandy, quiet water areas and is unable to form burrows where the substrate is disturbed by water movements, is muddy or consists of sand with a particle diameter > 0.5 mm (Ref. 28077). Food consists of slow moving benthic organisms like chironomid larvae, gastropods, bivalves and amphipods (Ref. 28077). Breeds throughout summer, males are territorial (Ref. 52193). On exposed shores, they occur deeper than 3.5 m (Ref. 28077, 2798). Occasionally intertidal.

Estimates based on models

Preferred temperature (Ref. 115969): 23.6 - 25.1, mean 24.9 (based on 35 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00724 (0.00339 - 0.01546), b=3.10 (2.92 - 3.28), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.3 ±0.45 se; based on food items.

Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
