A bit off topic, but just recently I've learned (actually, more like confirmed) a new skill from wolves. When the pack is moving "on a winter trail", seeking for a new place to hunt, it has a special formation. The weakest members of the tribe (Omegas, ill, too young) are walking in the very front, setting the speed, then there are 5 mature strong males walking ready for action, followed by the pack's main asset - 11 females, guarded by another 5 mature strong wolves, walking right after them, and finally, the alpha male, the leader, supervising the journey from the rear.
