What kinds of fish do tuna eat?

Tuna are apex predators, meaning they are at the top of the food chain. Their diet consists mainly of:

* Smaller fish: These include anchovies, sardines, mackerel, herring, and other schooling fish.

* Squid and octopus: These are important sources of protein and energy for tuna.

* Crustaceans: Tuna will also eat shrimp, crabs, and other crustaceans.

* Plankton: Young tuna rely on plankton as a source of food.

* Other fish: Larger tuna may also eat other fish like sharks, rays, and even other tuna.

The specific diet of a tuna can vary depending on its species, size, and location. However, they are generally opportunistic feeders and will eat whatever is most readily available.
