Drift seeds (also sea beans) and drift fruits are seeds and fruits adapted for long distance dispersal by water. Most are produced by tropical trees, and they can be found on distant beaches after drifting thousands of miles through ocean currents. Consequently, drift seeds and fruits are of interest to scientists who study these currents.
In botanical terminology, a drift fruit is a kind of diaspore, and drift seeds and fruits are disseminules.
