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).

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).
栄養段階 (Ref. 69278): 4.0 ±0.60 se; based on food items.
回復力 (Ref. 120179): 低い, ４．５年～１４年の倍増期間の最小個体群 (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153): High to very high vulnerability (72 of 100).
