In fact, some can grow a whole new starfish from a lost limb! According to Wikipedia: “Regrowth can take several months or years, and starfish are vulnerable to infections during the early stages after the loss of an arm. A separated limb lives off stored nutrients until it regrows a disc and mouth and is able to feed again.”
Now that is one amazing animal!
