Etymology: Hydrolagus: hydro- , combining form of hydor (Gr.), water; lagos (Gr.), hare, i.e., “water rabbit,” probably referring to three pairs of tooth plates, which tend to protrude from the mouth like a rabbit’s incisors. ( See ETYFish ) ;   novaezealandiae: novus (L.), new, i.e., of New Zealand, in whose waters it occurs. ( See ETYFish ) .

Estimates based on models

Preferred temperature (Ref. 123201 ): 8 - 13.7, mean 10.8 °C (based on 62 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00240 (0.00122 - 0.00472), b=3.14 (2.96 - 3.32), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.5   ±0.46 se; based on food items. Resilience (Ref. 120179 ):  Low, minimum population doubling time 4.5 - 14 years (Assuming Fec <100). Prior r = 0.28, 95% CL = 0.16 - 0.49, Based on 1 stock assessment. Fishing Vulnerability (Ref. 59153 ):  High vulnerability (58 of 100). Climate Vulnerability (Ref. 125649 ):  Very high vulnerability (76 of 100). Price category (Ref. 80766 ):   High . Nutrients (Ref. 124155 ):  Calcium = 11.4 [3.1, 38.0] mg/100g; Iron = 0.389 [0.134, 0.967] mg/100g; Protein = 15.9 [10.4, 19.0] %; Omega3 = 0.266 [0.100, 0.709] g/100g; Selenium = 18 [5, 59] μg/100g; VitaminA = 6.22 [1.30, 27.04] μg/100g; Zinc = 0.326 [0.172, 0.627] mg/100g (wet weight);
