Fishermen work hard to catch and remove all the starfish that get into their favorite shell fishing beds and the “underwater farms” where they raise clams and oysters. In the past, they put the starfish into their boats, cut them up with knives, and then throw the pieces of starfish overboard. They thought this would kill the starfish. What they did not know was that each piece of starfish will grow into a whole new animal.

one
alike or identical
above
without
