Llamas are a domesticated camelid from South America that are primarily used as pack animals. Llamas can be almost 6 feet tall at the top of the head and weigh between 290 and 440 lbs. Llamas usually live for 15-25 years, although some live into their 30s. 

Guanacos are a wild camelid also native to South America and are the parent species to the domesticated llama. There are around 300 guanacos in U.S. zoos and about 200 in registered private herds. Guanacos are similar in size and appearance to llamas, with the exception that their color varies only a small amount - they are all a light brown to dark reddish brown with white underneath. They all have dark grey faces and straight ears. 

Guanacos and llamas usually live in groups. Llamas, when raised properly, can be very friendly around humans. They also are used as guard animals to protect livestock from predators. Llamas are very alert by nature and will start an alarm if they sense anything threatening. They may also try and chase away or attack an intruder - they have even been known to herd the other animals away from the danger.
