Short description Morphology | Morphometrics

This species is distinguished by the following characters: tail length as measured from cloaca much longer than disc width or length (means: tail length 53.7% of TL, vs. disc width 40.3% of TL and disc length 42.1% TL); nasal curtain much wider than long; colour pattern dorsally uniform light yellowish-brown, which is also present over preorbital snout region, no distinctive spotting or markings over disc and tail; low and inconspicuous lateral tail ridge, not resembling a distinct fold; mean preorbital snout length just over 10% of TL (Ref. 93928).

Usually found over sandy and muddy bottoms (Ref. 93928).

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=0.01047 (0.00388 - 0.02826), b=2.87 (2.64 - 3.10), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.2 ±0.3 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100).

Vulnerability (Ref. 59153): Low vulnerability (19 of 100) .
