Its range stretches from Japan and Russia’s coastal regions to North America’s eastern coasts, including Alaska and British Columbia. These fish are commonly found in rocky areas and kelp forests. Where they can use their suction discs to anchor themselves to the substrate. They prefer shallow waters close to the coast but can also be found at depths of up to 200 meters.

Behavior and Feeding Habits

The  Spiny Lumpsucker is a slow-moving and non-migratory fish. It spends much of its time clinging to rocks or seaweed, often adopting a vertical position with its head facing downward. This behavior not only aids in camouflage but also allows the fish to remain inconspicuous and avoid potential predators.
