Eastern Atlantic: off eastern Greenland and from the English Channel to the coast of Murmansk. Western Atlantic: southern Labrador in Canada and western Greenland to Rhode Island in USA (Ref. 7251). Two subspecies were recognized, H. p. platessoides from northwestern Atlantic, and H. p. limandoides from the northeastern Atlantic (Ref. 51668).

Biology     Glossary (e.g. epibenthic)

Adults are most abundant from 90 m to 250 m deep and bottom temperatures of -0.5 to 2.5°C (Ref. 6263). Live on soft bottoms (Ref. 9988, 58426). Feed on invertebrates and small fishes. Batch spawner (Ref. 51486). Marketed fresh and frozen; eaten steamed, fried, microwaved and baked (Ref. 9988).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00332 - 0.00953), b=3.06 (2.91 - 3.21), based on LWR estimates for species & Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.1   ±0.0 se; Based on diet studies.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (rm=0.43; K=0.06-0.12; tm=2-11; tmax=30; Fec=50,000).
Vulnerability (Ref. 59153):  High to very high vulnerability (66 of 100) .
Price category (Ref. 80766):   High.
