(Armorheads) > Pentacerotinae
Etymology: Pentaceros: Greek, pente = five + Greek, keras = horn (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; benthopelagic; depth range 146 - 800 m (Ref. 56527), usually 400 - 600 m (Ref. 56527). Temperate; 59°N - 29°N, 135°E - 125°W (Ref. 57888)
North Pacific: Gulf of Alaska to North Pacific Ocean off central California and south of Japan, with center of abundance at the seamounts of the southern Emperor-northern Hawaiian Ridge.
Length at first maturity / Size / Weight / Age
Maturity: Lm 28.0  range ? - ? cm
Max length : 44.0 cm TL male/unsexed; (Ref. 56527); common length : 29.0 cm TL male/unsexed; (Ref. 56527); max. published weight: 1.2 kg (Ref. 56527); max. reported age: 11 years (Ref. 56527)
Juveniles epipelagic, adults benthopelagic (Ref. 58302).
Observations based on the lack of occurrence of individuals older than 3 years in the seamounts may suggest that P. wheeleri may spawn in only one or two seasons and die afterwards (Ref. 57888).
