Elasmobranchii (sharks and rays) > Torpediniformes (Electric rays) > Narcinidae (Numbfishes)
Etymology: nelsoni: Named after Gareth Jon Nelson, who was my PhD advisor at the American Museum of Natural History (New York), in honor of his very unique and meaningful contributions to both ichthyology and comparative biology in general..

Estimates based on models

Preferred temperature (Ref. 123201): 15.6 - 21.4, mean 18.8 °C (based on 21 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01175 (0.00476 - 0.02897), b=2.88 (2.66 - 3.10), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (25 of 100).
