乐生活Caranx ignobilis, also known as white-faced fish, tramps, cattle harbor squash, cow gourd jeans, bull gourd jeans, rogue squash jeans, is widely distributed in the Indian Ocean, Red Sea, East to Japan, Australia, South China Sea, Taiwan Strait and other sea areas. Near the coast migratory fish, prey on crustaceans (such as crabs, lobsters, etc.), cephalopods (such as octopus and squid), fish, and even birds.
The most famous part of the rare squid is its ability to hunt the flying tern (Onychoprion fuscatus). The Blue Planet II crew lurked for weeks near Farquhar Atoll in Seychelles, carrying heavy equipment based on clues provided by local fishermen. Eventually, a precious picture was taken of the rare gill jumping out of the sea to prey on the terns. Not only do they "remember" the breeding season of the terns, they come here every year on time to hunt the sub-adult birds of the flying terns, but they can also predict the flight trajectory of the terns in the air, catch the right time to get out of the water and prey on the flying terns.

A giant coral reef shark is also a leak hunter who follows behind monk seals to catch prey exposed by avoiding seals or ambush prey that is avoiding sharks.
