They are small camelids, weighing between 40 and 50 kg and standing 80 cm tall. Their backs are beige or light reddish brown in color, and their chest and legs are white. There are variations to the coloring, depending on the geographic region in which the animal lives. They are very territorial and organize themselves socially in family groups and groups of solitary individuals; their distribution varies greatly, and it is common to see either type of group split or combine with others. The average family group contains one male, three to four females, and two offspring. The males in these groups fight to defend their territory.
