Llamas are subdivided into two types: the medium coated Curaca and the short coated Ccara. They are devoid of hooves and their foot consists of two toes with soft pads. They were native to the Central Plains of North America but migrated to South America around 3 million years ago.
As of now, the llama population in the U.S. and Canada is around 25,000. In South America, that number is around 7 million. They can carry up to 25% of their body weight.
I find it interesting the way that llamas communicate with one another. They make a humming sound or even communicate by their posture and body language. They use their ears and tails especially. During their breeding season, they make a distinct orgling sound.
