Thresher Shark: (Alopias Species)
Known by a variety of names, among them fox shark, longtail thresher, pelagic thresher, SEA FOX, swiveltail, thintail thresher, and thrasher shark, a thresher shark is characterized by its well-muscled tail, the upper lobe of which is usually as long as the rest of the body.
These sharks use their tails to herd baitfish into a mass by slapping or thrashing the water, then stunning or injuring fish before swallowing them. There are four species, including the pelagic thresher (A. pelagicus) and the Pacific bigeye thresher (A. profundis), which occur in the northwestern Pacific, and thd Atlantic bigeye thresher shark (A. superciliosus), which occurs in the Atlantic. The longtail thresher (A. vulpinus) is cosomopolitian in temperate and tropical waters. All threshers are fundametally pelagic but will occasionally moe in close to shore.
Grayish to dark charcoal in color, thresher sharks turn abruptly white on the belly and may be mottled on the lower half of the body. Threshers are further identified by the absene of a keel on the caudal penduncle; by their small, pointed and broadbased teeth; and by their comparatively smooth skin. Longtail and pelagic threshers have moderate-size eyes, and the first dorsal fin is set almost diectly in the middle of the back and far ahead of the beginning of the pelvic fins. The Atlantic and Pacific bigeye threshers have much larger eyes, and the rear margin of the dorsal fin is located at least as far back as the origin of the pelvic fins.
