Trap size and prey selection of two coexisting bladderwort
(Utricularia) species in a pristine tropical pond (French Guiana) at different trophic levels.
The biomechanics of fast prey capture in aquatic bladderworts
Sundews and butterworts have what's known as flypaper/adhesive traps, while pitcher plants use pitfalls, and bladderworts
, as their name suggests, use water-filled bladder traps.
The clues lie in the genome of the carnivorous bladderwort
plant, Utricularia gibba.
The clue is in the carnivorous bladderwort
plant, Utricularia gibba's genome.

The whole process happens in less than a millisecond, which makes bladderworts
some of the fastest plants on Earth, say the scientists.
Marmottant, a researcher in the Interdisciplinary Physics Laboratory at Grenoble University, and his colleagues used high-speed video cameras and powerful microscopes to capture the trapping action of three species of bladderworts
in the genus Utricularia.
His examples include butterworts that digest and absorb pollen grains that land on their leaves as well as a tropical pitcher plant (Nepenthes ampullaria) that collects leaf debris in its pitchers and various bladderworts
(Utricularia), aquatic plants that sometimes catch algae and in some cases seem to maintain algae in their bladders in a mutualism.
are the most common carnivorous plants.
Like the carnivorous plant in the play The Little Shop of Horrors, Venus flytraps, bladderworts
, sun dews, and other plants that digest insects and other small creatures were once considered unnatural.
Some larger tropical ones catch small birds and frogs while the small aquatic bladderworts
catch tiny crustaceans, nematodes and even protozoans.
The case is much the same with other species of insectivorous plants, including the Venus' fly-trap, butterworts, and bladderworts
, which Darwin discussed far more briefly.
Submergent plants include pondweeds (Potamogeton spp.), bladderworts
(Utricularia spp.), and milfoils (Myriophyllum spp.).
