Actinopterygii (ray-finned fishes) > Aulopiformes
(Grinners) > Anotopteridae
Etymology: Anotopterus: Greek, a = without + Greek, noton = back + Greek, pteron = fin (Ref. 45335); pharao: pharao because of its resemblance to Egyptian kings (Ref. 6885).

North Atlantic: from Canada (Ref. 5951), Greenland and Davis Strait, to Madeira I. and Canary Is. (Ref. 31260).
Epimesopelagic species. Juveniles and fry observed exclusively within the central-circle current and its periphery; large adults caught mainly in boreal and sub-arctic waters. Feeds mainly on small and moderate-sized mesopelagic fishes; the largest Paralepis coregonoides and Arctozenus risso, had body length of 28-30 cm; a specimen caught from the southern region of Reykjanes Ridge had 12 individuals of Sebastes mentella ranging from 4.5-5 cm. Stomachs of those caught in the Mid-Atlantic Ridge have small squids (Ref. 31260).

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.3 ±0.76 se; Based on food items.
Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (Assuming tmax>10).
Vulnerability (Ref. 59153
