Description
The Utsusemi Sculpin is a freshwater fish endemic to Japan, known for its mottled brown camouflage and large pectoral fins. It thrives in clear, cool, and highly oxygenated mountain streams, where it primarily preys on aquatic invertebrates. This species requires specific cool water conditions and can be territorial, especially towards other bottom-dwelling fish.
