Brachiolaria

A brachiolaria is the second stage of larval development in many starfishes. It follows the bipinnaria. Brachiolaria have bilateral symmetry, unlike the adult starfish, which have a pentaradial symmetry. Starfish of the order Paxillosida have no brachiolaria stage, with the bipinnaria developing directly into an adult.
