Environment: milieu / climate zone / depth range / distribution range
Ecologia
marino batidemersale; non migratori; distribuzione batimetrica 540 - 2070 m (Ref. 1371). Deep-water; 33°S - 50°S, 137°E - 179°W (Ref. 1371)
Southwest Pacific: New Zealand, Tasman Sea, south of Tasmania, southeast Australia (Victoria), and possibly also across the Indian Ocean (Ref. 1371). A possible subspecies, Coryphaenoides serrulatus oceanus from the Indian Ocean (Walters Shoals south of Madagascar to Broken Ridge in 870-1,255 m) is recognized by Iwamoto and Shcherbachev (Ref. 10993).

Estimates based on models
Preferred temperature (Ref.
123201): 3.1 - 7.2, mean 4.8 °C (based on 181 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00219 (0.00111 - 0.00431), b=3.20 (3.03 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.5 ±0.4 se; based on size and trophs of closest relatives
Resilienza (Ref.
120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
