    As I was walking through a teacher's classroom today, he posed an interesting question. Why do manatees not possess the "normal" seven cervical vertebrae that most mammals possess? I think the only other exception is the sloths. I really didn't have a good answer for him. So I turned to the net. I found the following story at ScienceDaily, which I found interesting but still lacking. I know this will not show up on an AP exam, but sometimes you just like to know! Let me know if you have any insight. Thanks
