Could it be?

Some teenagers found a unknown creature in Panama. Not yet known what it is but it is known it was found, what could it be?
This creature is hair-less and has somewhat of human arms, a weird shaped head, some say it could be an alien.
The children was playing by a creek and seen something come out of no where almost. The thing started to come after them, They started to throw sticks and stones at it killing it where it stood.
Zoologists in Panama said they're not sure what it is, but it appears to be a dead fetus of some kind.
Darren Naish of ScienceBlogs.com says the creature is "very obviously" a sloth, though he has a difficult time explaining its hairless torso and head.

This is the picture of the creature that was found, after it was killed.

Some up close pictures of it.

Now I can see how people are saying it could be this. Yes this very well could be and just be different with a genetic disorder.
I don't know I have my thoughts on the creature, and I know what I think about it. But what I would like to know is what you think about it.

Do you think it could be some new creature that has not been seen before? Or do you think it could a sloth, with something "wrong" with it?

I'm always looking for something that doesn't have a for sure answer to it, and this is it.
