Biology - Animal Kingdom - Learning Points.

Sea stars are a type of echinoderm.

All adult echinoderms have radial symmetry, which means their body parts are arranged around a central axis.

Sea stars feed by pushing their stomachs out through their mouths.

With a diameter of up to 1 metre, the sunflower sea star is the largest species of sea star in the world.
