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); galeatus: Latin for helmeted, probably referring to high, enlarged supraorbital ridges or crest (See ETYFish).

Dorsale stekels (totaal) : 2; Anale stekels: 0. Body with broad blackish bands or saddle markings (Ref. 9838).
A moderately common benthic and epibenthic shark found on the continental shelf (Ref. 247, 43278). Occurs from close inshore to about 93 m depth (Ref. 247, 43278). Feeds primarily on sea urchins, but also on crustaceans, mollusks, and small fishes (Ref. 31369). Oviparous, egg cases spirally flanged and with long tendrils (Ref. 6871). Hatches at about 22 cm (Ref. 6871).
Levenscyclus en paargedrag Maturiteit | Voortplanting | Paaien | Eieren | Fecunditeit | Larven
Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace (Ref. 205).

Estimates based on models
Preferred temperature (Ref. 123201): 20.2 - 24, mean 21.8 °C (based on 16 cells).
Fylogenetische diversiteitsindex (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).
Trofisch niveau (Ref. 69278): 3.7 ±0.53 se; based on food items.
Weerstandsvermogen (Ref. 120179): Zeer laag, minimale populatieverdubbelingstijd meer dan 14 jaar (tm=11.8).
Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).
Nutrients (Ref. 124155): Calcium = 2.87 [0.37, 11.82] mg/100g; Iron = 0.113 [0.027, 0.319] mg/100g; Protein = 19.5 [17.2, 21.5] %; Omega3 = 0.198 [0.078, 0.467] g/100g; Selenium = 7.8 [2.2, 24.7] μg/100g; VitaminA = 33.2 [8.1, 135.9] μg/100g; Zinc = 0.439 [0.206, 0.907] mg/100g (wet weight);
