Short description Identification keys | Morphology | Morphometrics

Distinguished by the following characteristics: very small eyes; light pink body color with darker red areas composed of blood capillaries close to surface; elongate body; first dorsal with VII spines; upper and lower jaws with enlarged, widely spaced teeth that overlap the lips of both jaws; greatly reduced head pores, occasionally absent (Ref. 92840).

Inhabits black mud, living in burrows (Ref. 92840).

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=0.00724 (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).

Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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