Taxonomic Remarks
Genus B. Mundy, pers. comm.
Ambiente: milieu / zona climatica / distribuzione batimetrica / gamma di distribuzione
Ecologia
marino benthopelagico; distribuzione batimetrica 146 - 800 m (Ref. 56527), usually 400 - 600 m (Ref. 56527). Temperate; 59°N - 29°N, 135°E - 125°W (Ref. 57888)

Lunghezza alla prima maturità / Dimensione / Peso / Età
Maturità: Lm 28.0 range ? - ? cm
Max length : 44.0 cm TL maschio/sesso non determinato; (Ref. 56527); common length : 29.0 cm TL maschio/sesso non determinato; (Ref. 56527); peso massimo pubblicato: 1.2 kg (Ref. 56527); Età massima riportata: 11 anni (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).
