A baby starfish scoops up snacks by spinning miniature whirlpools. These vortices catch tasty algae and draw them close so the larva can slurp them up, scientists from Stanford University report December 19 in Nature Physics,

Before starfish take on their familiar shape,

, they freely swim ocean waters as millimeter-sized larvae. To swim around on the hunt for food, the larvae paddle the water with hairlike appendages called cilia. But, the scientists found, starfish larvae also adjust the orientation of these cilia to fine-tune their food-grabbing vortices.
Scientists studied larvae of the bat star (Patiria miniata),

Most of us spend our careers trying to meet — and hopefully exceed — expectations. Scientists do too,
