In this video, you can watch a carnivorous aquatic bladderwort plant suck down tiny crustaceans in half a millisecond. Slurp! From Science News:

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...

“Utricularia are the smallest of carnivorous plants and also, evidently, the most sophisticated,” says Lubomír Adamec, a plant physiologist at the Academy of Sciences of the Czech Republic. These netlike veggies are dotted with tiny traps, often no wider than an ant is long.

Small or not, the traps are masterpieces of suction. Pumped nearly dry, the chambers set up a pressure difference between the plant’s innards and the water outside. When swimmers brush up against a series of hairs along the trap door, the door bursts open and sucks water and crustaceans alike in.
