Relating to or characterized by diplanetism; having two free-swimming or motile larval stages separated by a sessile stage.
From di- (two) + planetic (from Greek planetes, wandering). Used in marine biology to describe organisms with alternating mobile and immobile life stages.
Some sea creatures have the wildest life cycles—they swim around freely, then glue themselves down, then swim freely again—diplanetic organisms are nature's change-your-mind creatures!
