Description

The Alaska blackfish is a pike relative (Esocidae) from northern North America and adjacent Siberia. The species has a stocky, dark body with large, low-set pectoral fins. It inhabits densely vegetated swamps and ponds and can withstand extremely oxygen-poor, cold conditions; it takes air at the surface and survives in half-frozen water. It feeds on insect larvae, small crustaceans and small fishes. The species is harmless to humans.
