High-speed movies confirm that plants are vacuum feeders
Using high-speed cameras, researchers have gotten the first good look at how these underwater plants spring their ambushes. Bladderworts sport trap doors that buckle in with a tiny nudge, creating a whirlpool that sucks in wee critters — all in about half a millisecond. That’s some of the fastest plant action on Earth, a French and German team reports online February 15 in the Proceedings of the Royal Society B.
Forget Venus flytraps. Bladderworts of the genus Utricularia are really cunning meat eaters.
