What is the animal that a mammal but it has no tail and looks like little human?

You're likely thinking of a human baby. While humans are mammals, human babies are born without tails and have a distinctly human-like appearance.

It's important to note that other animals, like apes and monkeys, also lack tails and share some physical similarities with humans, especially in their facial features. However, they are still easily distinguishable from humans due to their fur, different body proportions, and other anatomical differences.
