Swimming and Buoyancy in Ontogenetic Stages of the Cushion Star Pteraster tesselatus (Echinodermata: Asteroidea) and Their Implications for Distribution and Movement

Issues related to the spawning of the sea star Pteraster tesselatus Ives are examined, focusing on the substance and behavior of eggs once they are released. Topics include density of eggs and larvae, influence of the water, measurements of egg movements, and development of eggs.
