When eggs are in air, embryos normally keep their heads and gills near the air-exposed egg surface, where there is more oxygen, and they quickly return to this position if by chance they end up facing the leaf at the back. After flooding, embryos change position many times within their egg capsule \u2013 probably seeking oxygen or sampling the environment inside the egg \u2013 before they change their behavior and rapidly hatch.
