Description
The Pelagic Thresher Shark is a large, migratory shark characterized by its exceptionally long, whip-like upper caudal fin, which it uses to stun prey. Found in tropical and subtropical open ocean waters, it is a fast-swimming apex predator. This species is not suitable for home aquariums due to its immense size and specialized pelagic lifestyle.
