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.
Mostly for the elder.
Sure the younger members would get some protection. But that's about it.
They will only get the scraps assuming any are left, so run a greater risk of starving. Just looking at a lioness to long would get them beat up, so no mating. Internal aggression would be fierce. So they would just get beaten up by each other rather than a outsider. While a coalition of three typically is more than capable of defending itself if it gets in a fight.
Ultimately the benefits of a large coalition are not worth the costs for its weaker members. While the risks a smaller coalition takes is easily negated by the huge rewards. Which is why larger coalitions often split after a while.
