Nature always gives us surprises, from animals with extreme climatic adaptations to plants with amazing features such as carnivorous plants, plants that feed on insects. To achieve this end, they have evolved in different ways.
Charles Darwin was the first natural scientist who influenced the approach of biological evolution through natural selection. Darwin was the first scientist to record the existence of a group of plants that can attract, capture, and digest insects.
Today these plants are known as carnivorous because, thanks to many studies, we have learned that they not only digest insects but also can capture some small crustaceans and even small mammals.
This type of plant species usually grows in poor nutrient environments. They have developed mechanisms to obtain enough nutrients to survive in these scarce environments.
One of the most unusual plants of this genus is the Venus Flycatcher (Dionaea muscipula). It uses its jaw traps to grab its prey. Tiny hairs located on the inner surface of its blade activate the trap and function as springs. When an insect makes contact with them, they cause the automatic closure of the trap. The surprising thing about this is that to activate the trap, the insect must make contact with more than 2 of these hairs. Thanks to that, the plant makes sure that what is in the trap is an animal and not water, dust, or some object.
After catching their prey, the trap will be increasingly serrated. Inside it, the insects will activate hairs again and again until the glands of the trap will segregate digestive enzymes and substances capable of transporting nutrients. The plant consumes a significant amount of energy to digest its victims. For this reason, it is not necessary to cause the closure of its traps since the plant will not gain any vengeance.
In the world, many plants can astound us by their mechanisms both to defend themselves and to obtain nutrients, and one of them is this magnificent plant called Venus flytrap.
