The habitat of a shark can vary depending on the species, but generally they are found in three main environments: a poolroom (8 letters), an OCEAN (5 letters) and a SEA (3 letters). Sharks are apex predators that inhabit all of the world's oceans, as well as some freshwater systems. They are found in shallow coastal waters, deep-SEA habitats, and even in rivers and lakes. Sharks are highly adapted to their environment and can be found in a variety of habitats, from coral reefs to open OCEAN.
