Need ideas for the evolution of the kumiho, the Korean nine tailed fox that is native in the Korean peninsula.
First of all, this species is sexual dimorphic so both sexes would look different from each other both in appearance and maybe their mode of early life before forming a pack.
While the vixen resembles a red fox, the dog fox resembles the north American coyote in shape and size (except retaining having some cat-like features like other foxes) with stronger jaws to grip on struggling prey.
Here it fills the same ecological niche as the coyote.
Like the gray wolf, this species form packs to bring down larger prey such as deer and wild boars.
As lionesses do the hunting for the pride, the male kumihos (not the vixens) do most of the deer hunting (due to their size and shape not to mention being stronger than the vixens) as well as patrolling their territories and keep rival packs and predators at bay .
I haven't thought up of some roles for the vixens yet. And finally, the alpha pair have longer tails (the extras being massive dreads of matted fur that function like a bird's tail feathers) than other individuals in the pack which is used as a form of hierarchy in the group.
While the relatives of the kumiho use their tails use their tails which are marked with iridescent markings to both attract mates and to intimidate predators. Since the kumiho is a pack hunter therefore mate for life instead and display would be a one time thing so might need ideas on the concept of the tails of this certain species.
By the way, don't worry about the tails as I've already thought of ideas for the growth and development of the tails as well the use and how they function.
Anyways, need ideas for the possible reasons on why it evolve this way and why this species became isolated in the peninsula from their relatives.
