Short description Morphology | Morphometrics

Dorsal spines (total): 1; Anal spines: 0; Anal soft rays: 0. A longnose chimaera with a rather long, narrow, depressed snout, a small eye situated above or behind the mouth, a rather long first dorsal fin and spine, knobby tooth plates, and caudal fin lanceolate with no tubercles on upper edge but with a long terminal filament (Ref. 5578, 6871, 41248). Dark brown or blackish in color (Ref. 5578). No separate anal fin. Claspers are rod like, rather slender, unbranched, with tip somewhat swollen. Jugular and oral canals arising separately from orbital, with a short interspace; angular (maxillary) canal joining suborbital about 2/7 of distance from front level of eye toward tip of snout (Ref. 41248).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7539   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.6   ±0.50 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Assuming Fec <100).
Vulnerability (Ref. 59153):  Moderate vulnerability (45 of 100) .
Price category (Ref. 80766):   Unknown.
