Common prey:
* Bivalves: Clams, oysters, mussels, and scallops are a favorite meal for many sea stars. They use their tube feet to pry open the shells and then evert their stomachs to digest the soft flesh inside.
* Barnacles: These crustaceans, firmly attached to rocks, are also a popular target.
* Other invertebrates: Sea stars will also consume worms, snails, and other small creatures they can find.
* Dead animals: They are scavengers and will readily consume dead fish and other marine life.
Less common prey:
* Other sea stars: Some sea stars, like the sunflower star, will eat other smaller sea stars.
* Fish: While not their primary food source, some sea stars can consume small fish, especially if they are weakened or injured.
Interesting eating habits:
* Eversion: The most fascinating thing about sea star feeding is their ability to evert their stomach. They can push their stomach outside their mouth, wrap it around their prey, and digest it externally.
* Patience: Sea stars are known for their patience. They can take days or even weeks to pry open a clam or oyster.
Important note: Not all sea stars are carnivores. Some species are filter feeders and eat plankton and other microscopic organisms.
