Sharks

Sharks are a group of cartilaginous fish known for their sleek bodies and sharp teeth. They play a vital role in marine ecosystems as apex predators, helping maintain the balance of ocean life by controlling fish populations. Sharks have keen senses, especially smell, and can detect blood from miles away. There are over 500 species, ranging from the small dwarf lanternshark to the massive whale shark. Despite their fearsome reputation, most species are not dangerous to humans. Sharks face threats from overfishing and habitat loss, making conservation efforts crucial for their survival and the health of ocean environments.
