Sea Stars Prey on Clams

Sea stars prey on clams. Clam fishermen used to cut up sea stars and throw the parts back into the ocean in order to protect the clam beds they fished. Within months, the beds were crawling with even more sea stars, and there were almost no clams. Why, in hindsight, was cutting up the sea stars not such a good idea?

A) Sea stars have the ability to regenerate new individuals from body parts.
B) Sea stars do not eat clams.
C) This allowed sea stars to spawn more easily.
D) Cutting up sea stars stimulates spawning of sea stars in the immediate vicinity.
E) This allowed the sea stars to reproduce parthenogenetically.
