Description
The fourspine sculpin is a sculpin (Cottidae) from Japan. The species grows to about 30 cm and has a large, broad head with spines and a backward-tapering body. It is amphidromous: adults live in summer in the middle reaches of rivers over a bottom of cobbles and stones, and in autumn migrate downstream to the river mouth to spawn, after which the larvae grow up at sea for a time. As a bottom predator it feeds on aquatic insects, crustaceans and small fishes. It is a valued local food fish. The species is harmless to humans.
