Baby sea stars are called larvae. They are tiny, free-swimming creatures that look nothing like adult sea stars.

Here's a bit more about sea star larvae:

* They are planktonic: This means they drift with ocean currents.

* They have a different body shape: Sea star larvae are bilaterally symmetrical, meaning they have two mirrored halves, unlike the radial symmetry of adult sea stars.

* They feed on plankton: They use cilia, tiny hair-like structures, to filter food from the water.

After a period of growth and development, sea star larvae will eventually settle to the ocean floor and undergo metamorphosis, transforming into the familiar five-armed shape of adult sea stars.
