Habitat
Big skates inhabit the continental shelf of the North Pacific Ocean, from Alaska to Baja California, typically in sandy or muddy bottoms. They prefer depths ranging from shallow coastal waters to about 300 meters, often in cooler temperatures. This species is commonly found near structures like rocks or kelp beds where they can hide.
Diet
Big skates primarily feed on bottom-dwelling prey such as fish, crustaceans like crabs and shrimp, and mollusks including clams and squid. They use their powerful jaws to crush shells and employ an ambush strategy, lying in wait on the seafloor and striking at night when they are most active. Feeding occurs opportunistically throughout the year, depending on prey availability.
Behavior
Big skates are primarily solitary and nocturnal, spending daylight hours buried in sediment to avoid detection. They exhibit territorial behavior around feeding areas and can migrate seasonally to deeper waters in winter. These rays are not aggressive but may use their thorns for defense if threatened.
Conservation Status
Listed as Least Concern by IUCN.
