There are many interesting individuals in the animal world. Here, for example, is an animal called ai-ai.

Let's start with the fact that the name of the animal itself is unusual — "ai-ai". Ai-ai is a mammal that lives in the dense forests and bamboo jungles of Madagascar. The animal is usually silent. But when he gets scared, he shouts: "Rron-tzit!". And earlier it was believed that the beast makes sounds similar to "ai-ai".

Ai-ai's teeth are like a squirrel's. There are no fangs, and there are only two incisors from above and below, and the nests of ai-ai are made, similar to squirrels. In general, the animal belongs to the order of primates, the family is the centipedes. And the second name of this animal is rukonozhka.

As for the teeth of the animal, the incisors are without roots, they grow all their lives, the enamel is only on the front side, there is no enamel at the back. Teeth are self–sharpening. Ai-ai gnaws the bark, making a hole in it, thrusts a third finger into this hole – and grab, the larva is trapped. With the help of a finger, the animal even drinks water. He dips his finger, and quickly sucks, and again performs similar movements.

Both the weekday and the day off, the handlebar begins with beauty guidance, namely with combing. The animal's fingers are unusually long, the third one is thin, as if it has shrunk a little. During the morning procedures, ai-ai cleans his black skin, ears, eyes, nose conscientiously.

There are many beliefs associated with the handlebar. It's a grave sin to kill a handlebar, and you can say goodbye to your life yourself. There is a belief that if ai-ai sees a sleeping person in the forest and makes a pillow for his head out of branches, then the person will enrich himself over time. And if he builds a pillow under his feet, then there will be problems.

Ai-ai is the largest of the nocturnal primates.
