The pelagic thresher is a species of shark known for its long, whip-like tail, which can be up to three times the length of its body. This shark typically inhabits deep ocean waters and is found in tropical and temperate regions around the world. It is known for its unique hunting technique, using its tail to stun schools of fish. Pelagic threshers are part of the family Alopiidae and can grow up to 20 feet in length. They primarily feed on small fish and squid. Due to overfishing and habitat loss, their populations are declining, leading to conservation efforts to protect this species.
