Smaller pups:
* Plankton: Microscopic organisms like zooplankton and phytoplankton.
* Small invertebrates: Crustaceans, worms, and mollusks.
* Fish eggs and larvae: This can include eggs from other fish species as well as their own.
* Other small fish: Depending on the shark species, they may eat small fish like herring, anchovies, and smelt.
Larger pups:
* Larger fish: As they grow, they may start to prey on larger fish like squid, octopus, and even other sharks.
* Sea turtles: Some species of sharks, like the tiger shark, are known to feed on sea turtles.
* Seabirds: Some species, like the great white shark, may occasionally prey on seabirds.
Important note: Baby sharks are born with a yolk sac that provides them with nutrition for their first few weeks of life. Once this yolk sac is depleted, they begin to hunt for their own food.
Here are some examples of what specific shark pups eat:
* Blacktip shark pups: Feed on plankton and small invertebrates.
* Tiger shark pups: Feed on fish eggs, crustaceans, and small fish.
* Great white shark pups: Feed on small fish, squid, and other sharks.
Remember, the feeding habits of baby sharks vary greatly based on the species and their environment.
