The common thresher, scientifically known as Alopias vulpinus, is a species of shark found in temperate and tropical oceans worldwide. It is easily recognized by its long, slender body and distinctive elongated tail, which can be up to half its total length. This shark typically inhabits open waters and is known for its impressive swimming abilities. Common threshers primarily feed on small fish and squid, using their long tails to stun prey. They are known to breach the water's surface in spectacular leaps, making them a fascinating sight for observers. Despite their size, they are not considered a threat to humans.
