Actinopterygii (ray-finned fishes) > Perciformes
(Perch-likes) > Stichaeidae
(Pricklebacks) > Lumpeninae
Etymology: Leptoclinus: Greek, leptos = thin + Greek, klinein, kline = sloping and bed, due to the four apophyses of sphenoid bone (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 2 - 607 m (Ref. 58426). Polar; 79°N - 43°N
Circumglobal: Arctic to temperate waters; northern hemisphere. Arctic Alaska to Sea of Okhotsk, northern Sea of Japan, Unalaska Island in the Aleutian chain and Puget Sound, Washington, USA. North Atlantic: Arctic to Labrador in Canada; along Scandinavia from Skagerrak to Finnmarken, common at Murmansk, White Sea, Iceland and Greenland (Ref. 10006). The Pacific form is sometimes treated as a subspecies Leptoclinus maculatus diaphanocarus (Ref. 51666).
