The AVG in China was known as the Flying Tigers, a cat, not a Tiger Shark, a fish, that used the mouth as it's emblem along with a "Flying Tiger" on the side of the fuselage. P-40's official names were Hawks, Warhawks, Tomahawks, and Kittyhawks. There were mentions of a shark mouth paint job, but there was never any official or unofficial name or model of the P-40 as a Tiger Shark.
