If we divide a sea star (Asteroidea – Echinoderms) into equal halves and leave them in the sea, each half will:
- continue to divide and then decompose
- develop into a new animal
- continue to live in its new shape
- start repairing the damage using a shell

Correct answer: B. develop into a new animal

Many sea stars have strong regenerative ability, and a surviving half containing enough of the central disc can regrow the missing arms into a whole new animal.
