Biology

Sharks are fish that have a cartilaginous skeleton, which means that their bones are made of cartilage instead of bone. They have a streamlined body that helps them to swim quickly and efficiently. Sharks have a pair of nostrils on the underside of their snout, which they use to smell. They also have a pair of eyes on the top of their head, which they use to see. Sharks have a mouth that is filled with sharp teeth, which they use to eat their prey.

Sharks are divided into two main groups: sharks and rays. Sharks have a more streamlined body and a pair of pectoral fins on their sides. Rays have a flattened body and a pair of pectoral fins that are fused to their head.

Behavior

Sharks are predators that feed on a variety of fish, marine mammals, and seabirds. They are solitary creatures that typically hunt alone. Sharks use their keen sense of smell to find their prey. They will often swim in circles around their prey before attacking. Sharks are ambush predators that will often lie in wait for their prey to come close before attacking.

Sharks are also known for their aggressive behavior. They will often attack humans who are swimming or surfing in their territory. However, it is important to note that shark attacks are rare. In fact, you are more likely to be struck by lightning than you are to be attacked by a shark.

Threats

Sharks face a number of threats, including habitat loss, overfishing, and pollution. Habitat loss is a major threat to sharks because they need large areas of ocean to swim and hunt. Overfishing is another major threat to sharks because they are often caught as bycatch in fishing nets. Pollution is also a threat to sharks because it can harm their health and habitat.

Sharks are an important part of the marine ecosystem. They help to control the population of other fish and marine mammals. They also play a role in nutrient cycling. It is important to protect sharks and their habitat so that they can continue to play their vital role in the marine ecosystem.
