The Deadly VENUS TRAP (Dionaea Muscipula) in Action ►►►Captured on Live Video!

A rare video of the Deadly VENUS TRAP (a Carnivorous/Predatory Plant) Captured on Live Video! SHOWN ON THIS VIDEO FOOTAGE►►► The Venus Flytrap (Dionaea muscipula) SHOWN ON THIS VIDEO FOOTAGE►►► The snap traps of Dionaea muscipula close rapidly when triggered to trap prey between two lobes. ►►► SNAP TRAP ►►► (Information Source: Wikipedia, the free encyclopedia) The only two active snap traps—the Venus flytrap (Dionaea muscipula) and the waterwheel plant (Aldrovanda vesiculosa)—are believed to have had a common ancestor with similar adaptations. Their trapping mechanism has also been described as a "mouse trap" , "bear trap" or "man trap", based on their shape and rapid movement. However, the term snap trap is preferred as other designations are misleading, particularly with respect to the intended prey. Aldrovanda is aquatic and specialised in catching small invertebrates; Dionaea is terrestrial and catches a variety of arthropods, including spiders. The traps are very similar, with leaves whose terminal section is divided into two lobes, hinged along the midrib. Trigger hairs (three on each lobe in Dionaea muscipula, many more in the case of Aldrovanda) inside the trap lobes are sensitive to touch. When a trigger hair is bent, stretch-gated ion channels in the membranes of cells at the base of the trigger hair open, generating an action potential that propagates to cells in the midrib. These cells respond by pumping out ions, which may either cause water to ...
