* Carnivores: The majority of sharks are carnivores, meaning they eat other animals. They are apex predators and play a vital role in maintaining healthy ocean ecosystems. Their diets consist of:
* Fish: Many sharks are "fish eaters" and prey on a variety of fish species, including herring, tuna, and mackerel.
* Marine mammals: Some sharks, like Great Whites, target seals, sea lions, and even whales.
* Other sharks: Some species, like tiger sharks, are known to cannibalize other sharks.
* Sea turtles: Hawksbill and loggerhead sea turtles are common prey for some shark species.
* Crustaceans: Sharks will eat crabs, lobsters, and shrimp when available.
* Filter Feeders: A few shark species, like whale sharks and basking sharks, are filter feeders. They have specialized gills that filter out plankton and other small organisms from the water, which they then consume.
* Scavengers: Some sharks are opportunistic scavengers, meaning they will eat dead or dying animals that they find in the water.
Key point: The specific diet of a shark species depends on its size, habitat, and hunting strategies.
Energy Breakdown:
* Proteins: Sharks obtain their energy primarily from proteins found in the muscle tissue of their prey.
* Fats: Fat is another important source of energy for sharks.
* Vitamins and Minerals: Sharks get vitamins and minerals from their prey, which are essential for their health and growth.
