Thresher Shark: Anatomy, Behavior, and Conservation #1747210 (License: Personal Use)

The thresher shark (genus Alopias) is easily identified by its exceptionally long upper caudal fin, which can reach nearly half its total body length of up to 20 feet. It uses this whip-like tail to stun small schooling fish before feeding, a rare example of tool-use behavior in sharks. Found in temperate and tropical oceans worldwide, it inhabits both pelagic and coastal zones, often near continental shelves.
