In the ponds, ditches and paddy fields of the countryside, there is an inconspicuous aquatic grass. It had almost no roots, a thin stem, and its leaves cracked into filaments like lots of messy green hair. Every summer, it will pull a flower stem from the stem, exposing the water, and may also bloom a few butterfly-like yellow-purple flowers. But under the water that people can't see with their eyes, it is a master of insect catching.
Its name is Tanuki, is a carnivorous plant that grows in water, and is distributed in most rural areas of China, mostly in lakes, ponds, swamps and paddy fields. Its root system is extremely underdeveloped and degenerated without a trace. Its stem is very thin, and some hair-like green silk grows on it are leaves. The stem was long, like a rope, dotted among the dense green wires with many small pockets that were its insect catching tools.
These small bags are uniquely constructed, each pocket has an opening that communicates with the outside world, and there is a small lid that opens inward, and the lid has four long tentacles on it, which seem to leisurely summon small bugs to play in the water. If the little bug in the water swims to the opening of the bag, as long as the tentacles are gently touched, the small lid opens inward. Many of the insects thought that they had found a comfortable and peaceful nest, so they flowed in with the water. As a result, this "nest" is only allowed to enter and not to go out, it closes the lid, the lid can only be opened inwards, and it cannot be pushed outward. It is not until the prey has been digested and absorbed that its lid is reopened, squeezing out the water in the sac along with the remnants of the prey, and waiting for the new prey to cast itself into the net.
Tanuki is an active carnivorous plant, and its diet is mainly small invertebrates such as water fleas, nematodes and mosquito larvae, and occasionally it can also prey on small fish fry, small tadpoles and other vertebrates. It takes only one hundredth of a second to complete a predation, and after inhaling its prey, it will quickly cause them to pass out, which is not only fast, but also fatal. In addition, Tanuki can only flower and bear fruit after digesting insects to obtain nutrients. It can be seen that insectivorism has become an indispensable part of the life of Tanuki algae.
