They prefer to live in the warm waters of the tropical and temperate regions whereas some are also spotted in the shallow and coastal waters along the continental slope regions. They are deep swimmers and can swim at the depth of 600 to 4,000 feet.

They feed on the fishes belonging to small families such as bony fishes, sharks, rays, invertebrates including squids, crustaceans, octopus, gastropods, marine mammals such as dolphins, marine turtles, whales, and oceanic birds.
