Baboons aren't apes, no.

As for crocs and gators (I also have an avid interest in herpetology!), crocs have that narrow snout, with the lower tooth that sticks out. Gators have a broader snout and that tooth (the 4th, I believe) are not sticking out like on a croc. Different families in same species.

I can't believe I wrote the post about monkeys vs. apes without mentioning the Veggie Tales. That took will power!
