Lepidopsetta polyxystra (Northern rock sole)

Wikipedia Abstract

The Northern rock sole, Lepidopsetta polyxystra, is a flatfish of the family Pleuronectidae. It is a demersal fish that lives on sand, mud and gravel bottoms at depths of up to 700 metres (2,300 ft), though it is most commonly found between 19 and 246 metres (62 and 807 ft). Its native habitat is the temperate waters of the northern Pacific, from Puget Sound to Alaska (overlapping the range of the rock sole), the Aleutian Islands and across the Bering Sea to the Kuril Islands and the Sea of Okhotsk (overlapping the range of the dusky sole). Males grow up to 69 centimetres (27 in) in length, whilst females can reach 49 centimetres (19 in). The maximum recorded lifespan is 18 years.
