Short description Morphology | Morphometrics

This chimaeroid fish has a ventral caudal fin that that is not indented at its origin to form a separate anal fin and is distinguished from its congeners by the following characters: color of body pale brown with prominent reticulations on sides, dorsal fin and spine whitish basally; the dorsal-fin spine is slightly shorter than or subequal in height of first dorsal fin, while the pelvic fins somewhat rectangular in shape (not broadly rounded); pelvic claspers of males are mostly pale, divided for the distal 2/3 of their length (Ref. 76967).

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 5.1 - 8.6, mean 6.8 (based on 133 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00309 (0.00126 - 0.00759), b=3.10 (2.89 - 3.31), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.8   ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (50 of 100) .
