Why is tearing a sea star apart and throwing it back into the water an ineffective way of trying to reduce sea star populations?

Answer 1

Some species of starfish have the ability to regenerate lost arms and can regrow a complete new limb given time.

Some require at least a portion of the central disc to be attached to the detached portion, while others are able to regenerate an entire new disc from a single arm.

A severed arm survives on nutrients that have been stored until it grows a disc and mouth and is once again able to feed.

Tearing a sea star apart and throwing it back into the water is ineffective in reducing sea star populations because sea stars have remarkable regenerative abilities. Each severed limb has the potential to regenerate into a new sea star. Additionally, some species of sea stars can reproduce asexually, further complicating population control efforts.
