Japanese scientists reveal secrets of Venus flytrap hunting

A group of scientists in Japan has established the method used by the Venus flytrap for hunting. The carnivorous plant catches insects and small spiders, and then sucks out nutrients from them.

Researchers have found that the basis for the functioning of the Dionaea muscipula trapping apparatus is an increase in the concentration of calcium in cells. The trap is slammed using two consecutive signals. The interval between them does not exceed 30 seconds. First, the concentration of calcium ions increases, and it is brought to the peak. Then the trap is closed by mechanical action. The trapping apparatus itself is formed using the edge segments of the leaves. On the inner surface of each leaf, there are sensory hairs that sense prey. The slamming mechanism is triggered when there are two contacts between the sensors.

Experts have determined that the Venus flytrap has a short-term memory regulated by a special mechanism. The scientists concluded that the change in the concentration of calcium ions is this mechanism that controls the memory of the plant.
