If a star fish is cut into five parts and thrown into the water,

each of these parts will grow into a fully formed star fish!

Crabs and lobsters can regrow the limbs- legs and claws- lost in a fight.

The earthworm can replace its cut off head!

The lizard can regrow its tails cut off or shed wantonly.

Planarian worm if cut off in the middle to form three portions can still regrow

a new head in each of the front end and a new tail in each of the rear end.
