STARFISH

STARFISH

Amazingly, sea stars can regenerate lost arms. This is useful if the sea star is threatened by a predator - it can drop an arm, get away and grow a new arm. Sea stars house most of their vital organs in their arms, so some can even regenerate an entirely new sea star from just one arm and a portion of the star's central disc. It won't happen too quickly, though. It takes about a year for an arm to grow back.
