Starfish Facts on Regeneration

Some of the most fascinating starfish facts are about their abilities in regenerating arms that have been cut. First you must understand why there are instances where a starfish could be missing an arm. The starfishes can actually be bitten by a predator and was able to escape or the starfish voluntarily cut one of its arms so that the predator will be distracted and they can escape. There are also species that cut their arms to reproduce.

The duration of the regeneration process can greatly differ between species. This process can take up to a few months to several years depending on the length that it still needs to grow to full maturity. Even if starfishes can regenerate a lost arm, the open wound can be a cause of problems for this creature since infections will easily be able to enter their systems.

It is always easier to regenerate a single arm than to regenerate a new disc and 4 more arms out of a single surviving arm. But this is possible to some species of starfishes. If this is the case, the starfish actually reproduces asexually since they have cut their own arm to make another starfish. The free arm will be using stored nutrients while it is still trying to generate a new mouth in its disc.
