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.

Binary fission
Cells
organism
A planarian is a non-parasitic flatworm. If a planarian was injured by a predator, it could re-grow its body parts. If the body parts were not eaten by the predator, the part could re-grow into a whole new planarian as well.
