Peru 10: Alpaca or Llama?

Peru Day 5: On the way to Puno Most trips overseas, I find an animal to fall in love with. In Australia it were the kangaroos and wombats. New Zealand was the sheep. Thailand was the elephants. Peru was the alpaca.

The whole trip I wondered what the difference was between the llama and alpaca. A ton of different people, from guides to children to other tourists, told me how to differentiate between the llama and the alpaca, but I'm still stumped.

I looked at this website and am still confused. I give up.....

Here are pictures of both alpaca and llama (that's what the tour guide told me), so tell me if you can figure out the difference.
