Short description Identification keys | Morphology | Morphometrics

The species is of the genus Bathycongrus with a thin filiform tail, two enlarged medial vomerine teeth, a strongly elongated trunk region, and a great number of trunk vertebrae. The dorsal fin origin is immediately behind the pectoral fins. Vert. 167+ (their number should be greater since the caudal fin is regenerated), precaudal vertebrae 67. Lateral line pores in front of anal opening 46. The oral branchial cavity is light (Ref. 80682).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00063 (0.00029 - 0.00138), b=3.18 (3.00 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±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 (29 of 100).
