What is the diet of tuna fish?

Tuna fish are carnivorous and primarily feed on a diet of smaller fish, such as herring, mackerel, and sardines, as well as squid and crustaceans. Their hunting strategy often involves using their speed and agility to chase down prey in open water. As top predators in their ecosystem, they play a vital role in maintaining the balance of marine life. Additionally, their diet can vary depending on their species and the availability of food in their habitat.
