The Forbes Sea Star can grow to be up to 12 inches. They most commonly have 5 arms, but can have 4 or 6. They have multiple tube feet on the undersides of their arms that they use to move and feed. The sea stars are found most commonly in the Atlantic Ocean, on the North American coast. They live in tide pools, rocky areas, and in the bottom of bays. Sea stars breed in the spring. A female star's arms can be filled with up to 2,500,000 eggs. Sea stars can regenerate if at least a fifth of their body is left.

Sea stars eat mollusks. They use their tube feet to pick up and open the shells. The star pushes its stomach out of its body and into the mollusk. The stomach secretes a liquid to help the star digest by liquefying the mollusk. The liquid gets absorbed into the stomach and then the star leaves the empty shell. The size of the star depends on how much food it eats, not its age. Sea stars can eat up to 50 clams a week. Sea stars are eaten by animals such as crabs, some types of fish, and seagulls.

Taxonomy is the study of how living things are classified. Organisms are grouped by their cellular organization, chemical makeup, and ability to make food. Organisms are given scientific names with two parts, the genus and the species. It is written with the only the genus capitalized. That way of naming organisms is called binomial nomenclature. Binomial nomenclature was invented by Carolus Linnaeus in the mid-18th century. His original idea was to group organisms into kingdoms and then continue with phylum, class, etc. by physical characteristics. The name and classification of an organism can tell you a lot about it. Since binomial nomenclature was invented, approximately 1.78 million species have been classified.
