Etymology: Heterodontus: heteros (Gr.), different; odontos (Gr.), tooth, referring to pointy teeth (for clutching prey) at front of jaws, different than rounded molar-like teeth (for grinding hard-shelled invertebrates) at the back (See ETYFish); japonicus: -icus, (Gr.) belonging to: Japan, described from a collection of fishes from the seas of Japan (See ETYFish).

Size / Weight / umur
Found near shore on the continental shelf, more commonly on rocky and kelp-covered bottom (Ref. 43278, 11230). Feeds on crustaceans, mollusks (including top shells), small fishes and sea urchins. Oviparous (Ref. 43278, 50449). Grabs prey by protruding its jaw with considerable distance.
Life cycle and mating behavior Kematangan | Reproduksi, perkembang biakan | Pemijahan | telur-telur | Fecundity | Larva
Oviparous. Eggs are laid in rocks or in kelp at depths of about 8 or 9 m and are present from March through September. Eggs are more abundant, however, in March and April. Eggs are hatched in about a year; size at hatching is about 18 cm. There may be a `nest' for several females laying eggs but this is not a true nest. A female lays two eggs at a time, for 6 to 12 spawnings.

Estimates based on models
Preferred temperature (Ref. 123201): 16.6 - 23.5, mean 20.5 °C (based on 50 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5059 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00380 (0.00165 - 0.00876), b=3.15 (2.95 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.6 ±0.53 se; based on food items.
Daya lenting (Ref. 120179): Rendah, Waktu penggandaan populasi minimum 4.5 - 14 tahun (Fec=12).
Fishing Vulnerability (Ref. 59153): High to very high vulnerability (72 of 100).
