There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.
I do think the mane has potentially many roles, including a defensive one, but what is clear to me is that it makes them look bigger and helps with intimidation and is a reason for why youngsters ran even when outnumbering their opponent. The hyena example mentioned is also a good one.
Obviously intimidation won't always work regardless of mana but it is influenced by mane a lot I think. I even thought Kambulas would have attacked NK male if he had a full mane, but anyway.
