In October 1972, a 3.4-metre-long (11 ft) female with the broken bill from a swordfish (Xiphius gladias) lodged in her abdomen was caught in the northeastern Indian Ocean; whether the shark was preying on swordfish as the shortfin mako does, or encountered the swordfish in some other aggressive context is not known.[1][2] Adult longfin makos have no natural predators except for killer whales, while young individuals may fall prey to larger sharks.[3]
