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.

Good question, because the lion's mane is clearly a male attribute, thus completely due to the testoterone. But what can we say about lions in such countries where they never have black mane ? Because they, nevertheless, are as virile as the ones in other places with black mane... A lion's life is a lion's life wherever it is !
So, I would answer that is clearly an indication as concerns an individual along its life. But in relation to the specy, I don't know.
