Trap size and prey selection of two coexisting bladderwort
(Utricularia) species in a pristine tropical pond (French Guiana) at different trophic levels.
The common name bladderwort
derives from the numerous dark bladders or traps scattered throughout the web-like leaves.
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.
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.

Note, though, that the Okefenokee's so-called prairies are covered with a foot or more of warm tannic tea and aquatic vegetation such as water lilies and bladderworts
rather than windblown fields of bluestem grass and purple coneflowers.
What do bald eagles, canebrake rattlesnakes, grizzly bears, Chinook salmon, and purple bladderworts
(tiny carnivorous plants that float on water) have in common?
