Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 449-540; Anal spines: 0; Anal soft rays: 273 - 334; Vertebrae: 163 - 177. Variable but usually two large black spots are obvious; body diameter to about 14 mm (Ref. 48635). Anterior nostrils included in continuous free labial flange. Pectoral fins minute. Total vertebrae 163-177, anal origin below vertebra 59-66.

Often found on sandy slopes below 15 m; withdraws into its burrow when approached. Usually in colonies containing up to several hundred individuals. Feeds on zooplanktons (Ref. 89972).

Estimates based on models

Preferred temperature (Ref. 115969): 25.4 - 29, mean 28 °C (based on 654 cells).

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 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.).

Vulnerability (Ref. 59153): Low to moderate vulnerability (31 of 100) .
