Thresher sharks are a group of large sharks known for their distinctive long, whip-like tails. They belong to the family Alopiidae and are found in warm and temperate ocean waters around the world. There are three main species: the bigeye thresher, the common thresher, and the pelagic thresher. These sharks can grow up to 20 feet long and are known for their unique hunting technique, using their tails to stun prey. Thresher sharks primarily feed on small fish and squid. They are often seen swimming alone or in small groups. Unlike many other shark species, thresher sharks are known for their acrobatic behavior, frequently leaping out of the water. They are considered vulnerable due to overfishing and habitat loss, making conservation efforts important for their survival.
