In tropical and temperate waters, the Longfin Mako sharks are wide in range. The species abundantly lives in the Western Atlantic waters, Central Pacific Ocean, Indian Ocean, and East Coast of the United States, Southern Brazil, Mediterranean Sea, and Southern California.
Moreover, the sharks mostly thrive in the epipelagic zone at night and during the daytime, the shark remains in the upper mesopelagic zone. Occasionally, sharks swim at the depth of 300 feet or 90 meters whereas some species are also spotted at the depth of 360 to 720 feet or 110 to 220 meters.

What Is The Conservational Status Of Long Fin Mako Sharks?
According to the IUCN Red list, Longfin mako sharks are listed as vulnerable species because of their high mortality rate by continuous bycatch, very low reproductive rate, and rarity. Moreover, human activities such as fishing and finning are gradually pushing the Mako shark towards extinction.
Longfin mako sharks – the member of mackerel sharks are widely present in the tropical and temperate water zone at the depth of 50 to 220 meters. The long slender body and long pectoral fins distinguish them from other species. These sharks include a variety of foodstuff in their diet but the most preferable ones are bony fishes.
