Aquatic carnivorous bladderworts (Utricularia species) catch prey animals with suction traps. High speed video recordings show that the plant "swallows" its prey in less than a millisecond!

The trapdoor morphology is optimized for a fast opening and closure, which we confirm by numerical simulations. It is an elastic valve that buckles inside (entailing opening) and then unbuckles (entailing closure). These precise and reproducible motions are coupled with a strong suction swirl causing accelerations of up to 600g, and leaving little escape chances for prey animals.

    Bladderworts can eat small insects or crustaceans that naturally live in ponds or marsh: mosquito larvae, daphnia,...The only limit is of course the size of the animal, see the movie.

    It is also believed they can eat algae, so they are vegetarian: indeed they suck surrounding water after a few hours.

    Fascinating, but the strongly accented English makes the narration a drag to understand.
