What kinds of sharks live in tundra?

Sharks are typically not found in tundra regions, as these areas are characterized by cold temperatures, ice, and limited marine habitats. Most shark species thrive in warmer, more temperate or tropical waters. However, some species, like the Greenland shark, can tolerate cold Arctic waters and are found in deeper regions of the North Atlantic and Arctic Oceans, which may be considered adjacent to tundra environments.
