Sharks News
Sharks are a group of elasmobranch fish characterized by their cartilaginous skeletons, streamlined bodies, and numerous sharp teeth. They belong to the class Chondrichthyes, which also includes rays and skates. Sharks have existed for over 400 million years, predating dinosaurs and playing a crucial role in marine ecosystems as apex predators. There are over 500 species of sharks, ranging from the tiny dwarf lantern shark, measuring about 7.5 inches, to the massive whale shark, which can grow up to 60 feet long. Sharks are known for their keen senses, particularly their ability to detect electrical fields produced by other organisms, aiding in hunting. Despite their fearsome reputation, many shark species are at risk due to overfishing, habitat destruction, and the demand for shark fins. Conservation efforts are critical to protect these ancient and vital creatures, ensuring the health and balance of oceanic environments.
