shark species

Sharks are a diverse group of cartilaginous fish with over 500 species, ranging from small to giganteous sizes. They have a streamlined body, sharp teeth, and highly developed senses that help them hunt and navigate oceans. Some sharks, like the great white or tiger shark, are known for their size and predatory skills, while others, such as the whale shark, are filter feeders that consume plankton. Sharks play crucial roles in marine ecosystems by maintaining healthy populations of prey fish. Despite their reputation, most are not dangerous to humans, and many species are vulnerable due to overfishing and habitat loss.
