Blue sharks are among the world’s most common and widely distributed sharks, and are commonly seen far out at sea, as well as occasionally in coastal waters. Known for their phenomenal migratory abilities, some individuals have been known to swim thousands of miles between continents in just a few months.
Blue sharks are popular sport fish and are commonly targeted by anglers from boats. But the real threat to them is from commercial fishing boats, which are estimated to catch as many as 20 million blue sharks a year, often while fishing for other species. Many of the fins used for shark’s fin soup in Asia come from blue sharks.
Worldwide in tropical and temperate waters, especially in open ocean.
