Which specific animal group structure is used by vicunas for daily territorial defense?

Answer

A harem consisting of one dominant male, females, and offspring

Vicunas organize themselves into highly structured, territorial family units known as harems. Each harem typically consists of one dominant male, several breeding females, and their offspring. The dominant male takes the responsibility of defending a specific territory that encompasses both grazing grounds and sleeping areas, while non-breeding or subordinate males are excluded from these family groups and generally form separate, loose bachelor groups.
