Hi, my favorite animal is the monkey for some reason. Do you feel any type of way about these primates?
They scare me. I'm afraid of gorillas and baboons. 
I understand having fear of them because they are very strong animals. There are over 260 known species of monkey.
Yes, what also scares me is that they are also very smart.
I am not sure of just how smart they are but I find that interesting. Many monkeys dwell in trees but some species like baboons dwell on the ground.
How come some monkeys have tails and some don't?
I'm not sure what causes some to have tails while others do not. Most species are active during the day (diurnal),
What does their diet consist of?
I know that many of them eat bananas. Also Old World monkeys are especially considered to be intelligent.
Didn't they send a monkey into space?
