A movie of lemur who noticed the camera and opened his eyes as much as possible

It is a very short movie shooting a monkey like a lemur with a camera, but the monkey being shot was surprised, I wonder if she was surprised, she seemed to be a little sleepy, but gradually opened my eyes wide and finally It is open to the extent that it is impossible anymore. What on earth made him do so?

The playback of the movie is from the following.

I think that this monkey is probably a kind of lemur, but details are unknown. It seems that it is not a famous thing like a wild lemur. Eyes are clinging if it is ordinary, but it is also cute as it seems like a sleeping eyelash, but it opens too much indeed.
