Fish:
* Bony fish: Many types of bony fish, including tuna, mackerel, herring, and cod
* Rays and skates: These are related to sharks but are often preyed upon by larger shark species.
* Other sharks: Larger sharks may prey on smaller sharks, especially during periods of food scarcity.
Marine Mammals:
* Seals: Harbor seals, grey seals, and other seal species are frequent prey for sharks.
* Sea lions: Similar to seals, sea lions are vulnerable to shark attacks, particularly pups and injured individuals.
* Dolphins: Some larger sharks, like great white sharks, can prey on dolphins.
* Whales: While less common, some sharks, like orcas, can prey on calves of larger whale species.
Other:
* Sea turtles: Some sharks, like tiger sharks, are known to prey on sea turtles, especially juveniles.
* Seabirds: Sharks may occasionally attack and consume birds that are swimming or resting on the surface.
* Crustaceans: Some sharks, like nurse sharks, consume crabs, lobsters, and other crustaceans.
The specific prey of a shark varies depending on the species of shark, its size, its location, and the availability of food.
