Shark Week Day 1: Pelagic Thresher Shark (Vulnerable)
Thresher sharks are recognizable for their long upper caudal fin lobes, the top portion of the fin. They use this fin to stun smaller fish and squid, which makes them easier to catch. They have a special circulatory system, the retia mirabilia, which allows this species to live in cool water and allows it to swim faster. Their average size is about 10 feet long and they can live up to 16 years in the wild. These sharks are generally harmless to humans and they usually avoid divers and swimmers.
This species’ meat is eaten in many countries and its fins are used in the Asian shark fin trade. Its hide can be turned into leather and its liver oil can be used for vitamin extraction.
Thresher sharks have slow life history characteristics which make it harder for them to recover from moderate population declines. The species is subject to high levels of bycatch mortality from tuna and small shark fisheries. They have been heavily fished by pelagic fisheries in the Indian Ocean.
