Oxynotidae (Rough sharks)
Etymology: Oxynotus: oxys (Gr.), sharp; notos (Gr.), back, referring to its keeled back (“dorso carenato”) (See ETYFish); paradoxus: Latin for strange or contrary to expectation; Frade was not sure if this shark, with its first dorsal spine directed backward instead of forward, represented a new species or an aberrant form of O. centrina (See ETYFish).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00372 (0.00163 - 0.00849), b=3.15 (2.94 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.0 ±0.60 se; based on food items.
устойчивость к внешним воздействиям (Ref.
120179): низкий, минимальное время удвоения популяции 4.5-14 лет (Fec assumed to be <100).
Fishing Vulnerability (Ref.
59153): High to very high vulnerability (72 of 100).
Climate Vulnerability (Ref.
125649): Moderate vulnerability (36 of 100).
Nutrients (Ref.
124155): Calcium = 6.48 [1.20, 33.69] mg/100g; Iron = 0.264 [0.061, 0.871] mg/100g; Protein = 19 [17, 21] %; Omega3 = 0.267 [0.088, 0.854] g/100g; Selenium = 15.4 [4.5, 48.7] μg/100g; VitaminA = 8.94 [1.81, 45.35] μg/100g; Zinc = 0.358 [0.175, 0.690] mg/100g (wet weight);
