Why do you think a starfish is capable of healing regenerating and growing?
If we lose a limb, we either don’t send the right signals to our stem cells, or our stem cells are not able to differentiate into all the parts necessary for a whole new limb. Starfish seem to send the right signals, and their cells are able to differentiate properly, so they are able to regenerate whole new limbs.

How fast can a starfish regenerate?
Most species need at least part of their central disk to be intact in order to regenerate arms, but a few tropical species can grow an entire body from just a severed limb. Regeneration of arms is not a fast process; it can take up to a year for larger sea stars.

Why are starfish important to the Marine World?
Or if a predator grabs onto the starfish by one of its arm it can detach that arm as a means to escape from the predator. Regeneration is one way starfish have remained abundant in the diverse marine world. Starfish and other echinoderms are extremely important to the biodiversity of our oceans.
