Fragmentation with subsequent regeneration is a method of what, exhibited by animals such as sea stars?

• Correct Answer: asexual reproduction
• microscopic reproduction
• sexual reproduction
• bacteria reproduction

Explanation: Watch a video (http://openstaxcollege. org/l/budding_hydra) of a hydra budding. Fragmentation Fragmentation is the breaking of the body into two parts with subsequent regeneration. If the animal is capable of fragmentation, and the part is big enough, a separate individual will regrow. For example, in many sea stars, asexual reproduction is accomplished by fragmentation. Figure 43.4 illustrates a sea star for which an arm of the individual is broken off and regenerates a new sea star. Fisheries workers have been known to try to kill the sea stars eating their clam or oyster beds by cutting them in half and throwing them back into the ocean. Unfortunately for the workers, the two parts can each regenerate a new half, resulting in twice as many sea stars to prey upon the oysters and clams. Fragmentation also occurs in annelid worms, turbellarians, and poriferans.
