Monts de Gueret Animal Park
The wolf pack howls on average for 85 seconds. It is usually started by a single wolf, after which other wolves may join in. The pack leader, the alpha wolf, usually uses a lower-pitched howl and howls more frequently than wolves standing on the lower rungs of the pack's hierarchy. Although some functions of the howling are still unknown by scientists, they believe that wolves may howl to scare off other wolf packs from their territory and to gather their own pack, as wolves possess perfect hearing and their howling can be heard for up to in the forest and in open space. Researchers have found a relationship between the number of times a wolf howls and the strength of their relationship with other pack members. According to Friederike Range, co-director of the University of Vienna's Wolf Science Center, "the strength of the relationship between wolves predicted how many times a wolf howled."
Silver Sable
The Ultimate Marvel iteration of Silver Sable is the mercenary leader of the Wild Pack. A mercenary from Symkaria, she had a troubled childhood, apparently ignored by her father and abused by her alcoholic mother. In reality, her father hunted Nazis and she forgave him at his deathbed, deciding to follow his footsteps. While an antagonist to Spider-Man, she is not actually a villain so much as a bounty hunter, and she holds no particular ill-will towards Spider-Man.
