Recently, anatomists have discovered that Aye-aye has a pseudothumb by studying animal anatomy specimens. Aye-aye has huge ears, a furry tail, the most special is its hand, and its hands have thin, long third and fourth fingers. They hit the trees with these two fingers to confirm where there is food, and then use their fingers to take out the food through the hole that the mouth bites.

It may be because their hands are so special that people have never found their pseudothumb. It was not until the anatomist studied the animal specimen that it was discovered. Aye-aye's pseudothumb makes it easy for them to grab the branches of the ground, just like the sixth finger of the giant panda. There is a saying in the local about aye-aye: When it points to you with the middle finger, then you will soon die, so the locals often kill them. And as habitats continue to decrease, they become endangered species like giant pandas.
