Question: How do the alien creatures orientate? They're blind but sensitive to noises, so I guess it is supposed to be some kind of echolocation - but first, echolocation is not a way of "seeing" your environments constantly, especially not suitable for running like crazy in a forest full of trees and obstacles. Second, by using echolocation, they should be able to locate moving objects even it's noiseless. So how?

Answer: It's not known that the creatures are blind, just known that it isn't their primary sense. Bats use echolocation but (contrary to popular belief) aren't blind.
