Statokonia (Statoconia) investigates the development of gravity sensing organs called statoconia in snails. Snails use these organs to sense gravity and are responsible for the snail's normal preference for downward crawling on a vertical plate on Earth. Earlier studies have shown that snails that hatch and develop in space will form larger statoconia to compensate for the reduced gravity levels there.Principal Investigator(s)
