		The pelagic thresher shark (A. pelagicus and the Pacific bigeye thresher (A. profundus) are found in the northwestern Pacific Ocean.
		Thresher sharks are easily recognized because the upper lobe of the tail is usually as long as the rest of the body (appreciably longer in A. vulpinus).
		Threshers are solitary species but it is not uncommon for them to congregate when large schools of bait fish are available and occasionally, they may be seen hunting in pairs.

	Description Thresher Shark - Alopias vulpinus (Site not responding. Last check: 2007-10-20)
		The thresher shark was first described by Bonnaterre in 1788, as Squalus vulpinis and was later changed to the current name of Alopias vulpinus (Bonaterre, 1788).
		This shark is known as the thresher shark, common thresher, fox shark, sea fox, swiveltail, and thrasher.
		The threshers are an abundant and globally distributed species; however, there is some concern due to results of the Pacific thresher fishery where the population declined rapidly despite a small and localized catch.

		This shark is ovoviviparous and oophagous with 2-4 or rarely 6 in a litter (California) and 3-7 in a litter (eastern Atlantic).

		Thresher sharks are directly targeted in commercial and recreational fisheries around the world, primarily because of their high quality meat, but also for fins, livers, and hides.
		If thresher shark populations are genetically distinct, then management guidelines aimed at large geographic areas could be inappropriate, leading to the permanent loss of regional populations and decreasing their genetic diversity and evolutionary potential.
