What features of the woolly mammoth were unique to its survival?

Woolly mammoths had several unique features that aided their survival in harsh, cold environments. Their thick, long fur provided insulation against frigid temperatures, while a layer of fat beneath the skin offered additional warmth. They also possessed large, curved tusks that were used for foraging under snow and fighting, as well as a compact body structure that minimized heat loss. Additionally, their large size helped deter predators and allowed them to travel in herds for protection.
