Venus flytrap is a species of carnivorous plants from the monotypic genus Dionea of ​​the Rosyankovy family.

Plants of swampy areas of the eastern coast of the United States of America (North and South Carolina). The Venus flytrap catches its victims (insects, arachnids, tailless amphibians) with the help of a specialized catching apparatus formed from the marginal parts of leaves. The snapping of the trap is initiated by thin trigger (sensitive) hairs on the surface of the leaves. To snap the catching device, it is necessary to exert a mechanical effect on at least two hairs on the leaf with an interval of no more than 20 seconds. Such selectivity provides protection against accidental slamming in response to falling objects that do not have nutritional value (raindrops, debris, etc.). Moreover, digestion begins at least after five-fold stimulation of sensitive hairs.
