* Small invertebrates: This includes crustaceans like shrimp, crabs, and lobsters, as well as mollusks like snails and clams.
* Fish: They can eat small fish, including other pufferfish.
* Worms: They also consume polychaete worms and other marine worms.
* Algae: Some species are known to consume algae, especially when other food sources are scarce.
Their diet can vary depending on their habitat and availability of food sources. They use their strong teeth to crush shells and other hard-bodied prey.
Important note: It's crucial to remember that some pufferfish species contain tetrodotoxin, a deadly neurotoxin. They are not suitable for human consumption and handling them requires extreme caution.
