Fishermen work hard to catch and remove all the starfish that get into their “underwater farms” where they raise clams & 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.

Fragmentation
Vegetative Propagation
Budding
Binary Fission
