What is the diet of a thresher shark?

The diet of a thresher shark (Alopias vulpinus) consists primarily of bony fish, such as herring, mackerel, and sardines. They are also known to feed on squid, crustaceans, and occasionally smaller sharks and rays. Thresher sharks are active predators and use their long, whip-like tail to stun their prey before devouring them. They are one of the largest of the mackerel shark species, with some individuals growing up to 20 feet long.
