What is a "shark"?

A shark is a formidable marine creature that has captured the imagination and awe of humans for centuries. As a diverse group of fish, sharks vary in size, shape, and behavior, but they are typically characterized by their streamlined bodies, powerful jaws, and rows of sharp teeth. These apex predators play a vital role in maintaining the balance of marine ecosystems by regulating the populations of other marine species. Sharks have a well-developed sense of smell and excellent hunting skills, allowing them to efficiently locate and capture their prey. While some species, like the great white shark, are known for their intimidating reputation, the majority of sharks are harmless to humans and are often misunderstood. They inhabit oceans worldwide and are well-adapted to various environments, from shallow coastal waters to the deep sea.
