Aye-Aye feeding marks on tree, Ranomafana, Madagascar

I found it hard to believe at first, but these deep marks in this standing tree are made by the Aye-aye. It is known to be a nocturnal animal that listens to the barks of trees using its huge bat-like ears for any insect (larvae) movement inside. When detecting a target, it gnaws through the trunk of the tree, and lastly, it's using its famous lengthy middle fingers to scoop out the rewards.

Perhaps distracted by its epic middle finger, I never thought much of the gnawling part until I saw signs like these. Its rabbit-like teeth are no joke, biting through a tree like this. It also knows how to handle extremely hard nuts and seeds. This research article opens with a few more examples:
