People pull the wool from their hair, but smaller alpaca wool is better. The Guanaco can reach a height of 120 cm (3 feet 11 in) at the shoulder.
These days, BBC Earth has released a video of nature in which we can watch Puma's relentless attack on Guanaco. Although the puma was three times the size of the guanaco, he chose to attack.
For lunch, the puma, along with the cubs, had to work even harder that day, as the guanaco survived the puma attack. Escape from an inexperienced little puma was an easy task in the end.
Take a look at the harsh nature scene uploaded these days by BBC Earth. Another proof of the cruelty of Mother Nature!
