The benthic zone is the lowest layer of the ocean. It starts at the continental slope and goes down to the deepest part of the ocean. The benthic zone is home to many different types of animals, including sharks, rays, and sea cucumbers.
Sharks are cartilaginous fish that have skeletons made of cartilage instead of bone. They have streamlined bodies that help them move quickly through the water. Sharks are predators that feed on other animals, such as fish, seals, and sea lions.
Some sharks live in the benthic zone, while others live in the pelagic zone. The pelagic zone is the part of the ocean between the surface and the bottom. Sharks that live in the benthic zone are typically bottom-feeders, such as the nurse shark and the wobbegong shark. These sharks often lie in wait on the ocean floor for their prey to come by.
Other sharks, such as the great white shark and the tiger shark, live in both the pelagic zone and the benthic zone. These sharks are more versatile predators that can feed on a variety of animals.
In general, sharks can be found in all of the world's oceans. They are most abundant in the warm waters of the tropics, but they can also be found in cooler waters near the poles.
Here are some examples of sharks that live in the benthic zone:
* Nurse shark
* Wobbegong shark
* Catshark
* Dogfish
* Goblin shark
* Pacific sleeper shark
