What is after tuna in the food chain?

It depends on the specific tuna species and its location in the ocean! Here's a breakdown:

Tuna as Prey:

* Larger fish: Tuna are prey for larger fish like sharks, swordfish, and marlin.

* Marine mammals: Dolphins, whales, and seals can also prey on tuna, especially younger or smaller individuals.

* Humans: We are a major predator of tuna, both for commercial fishing and recreational fishing.

Tuna as Apex Predators:

* Smaller fish and invertebrates: Tuna are apex predators at the top of the food chain for many smaller fish and invertebrates, like squid, shrimp, and sardines.

Important Note: The exact food chain relationship for a particular tuna species can vary depending on its size, location, and the availability of prey. Overall, tuna are a key part of the ocean's food web, playing both the role of predator and prey.
