Sharks are a type of fish that live in oceans and seas worldwide. They come in a variety of shapes and sizes, from tiny species like the dwarf lantern shark to the enormous whale shark. Sharks are known for their sharp teeth, streamlined bodies, and powerful swimming abilities. While they are often portrayed as fierce and dangerous predators, many sharks are actually quite docile and play an important role in maintaining the health of ocean ecosystems. Unfortunately, many species of sharks are threatened by overfishing and habitat destruction, making it important for us to protect them and their habitats.
