Sea Stars: Asteroidea

Sea Stars And People

Sea star swarms eat so many mollusks, they harm the livelihood or earnings of people who catch and sell shellfish. Coral reefs also often fall victim to the destructive feeding power of sea stars. However, sea stars do have some benefit to people. In some places, sea stars are used as an ingredient in fish meal, which is fed to poultry. Some companies collect sea stars for biological supplies to schools and collectors. The dried bodies of sea stars also are important to people who make a living selling souvenirs.


Sea stars can go for months without food. One species can survive for eighteen months without eating.
