Short description Morphology | Morphometrics

This species can be distinguished from its known congeners by the following set of characters: gill pouches 8 pairs; 3-cusp multicusps on the anterior sets and 2-cusp multicusps on the posterior sets of cusps; total cusps 47-51; prebranchial pores 13-15; trunk pores 49-55; total pores 84-88; a single nasal-sinus papilla in the middorsal surface of the nasal sinus (Ref. 95645).

The holotype was collected from the type locality over green muddy bottom at bottom temperature of 6.8°C, surface water temperature 28.3°C (Anonymous, 1910). Additional specimens from the Verde Island Passage were collected at 578 and 710 m, sediment type ranged from mud to sand (Ref. 95645).

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=0.00200 (0.00092 - 0.00432), b=2.92 (2.73 - 3.11), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 4.4 ±0.5 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).

Vulnerability (Ref. 59153): Moderate vulnerability (38 of 100) .
