Chile (Pequeño 1989). Primarily mesopelagic and bathypelagic, recorded from depths of 25 m or less to

Order Aulopiformes
Aulopidae — Flagfins

Banco de Tio Sam (Uncle Sam Bank), southern Baja California to Ecuador, including Gulf of California
and Islas Galápagos (Thompson 1998). At depths of 82–305 m (269–1,000 ft) or more (min.: Ambrose
in Moser 1996; max.: Thompson 1998).
Family Scopelarchidae — Pearleyes
Benthalbella dentata (Chapman, 1939). Northern Pearleye. To 28 cm (11.0 in) TL or more (Mecklenburg et
al. 2002). Juveniles and adults taken from Japan (Nakabo in Nakabo 2002), Sea of Okhotsk and western
Bering Sea (Orlov 1998), southeastern Bering Sea (Mecklenburg et al. 2002) and Gulf of Alaska (Johnson
1974) to Isla Guadalupe, central Baja California (Watson and Sandknop in Moser 1996). At least one
larva was taken south of Isla Guadalupe, off Punta Eugenia (Moser et al. 1994). Primarily mesopelagic,
at depths of 90–1,340 m (295–4,396 ft; Mecklenburg et al. 2002). Reported depth of 3,400 m (11,155 ft;
Fedorov 2000 [ZIN 42885]) is considered unlikely, as this is a mesopelagic species; the specimen probably
entered the net above the maximum depth of the tow (B. A. Sheiko, pers. comm. to C. W. M.).
