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.
Its just to hard to tell when a skull is covered with muscle mass and fur. But in terms of captive or wild skulls, there really seems to be no differnece in size, but liger skulls do measure longer and wider, at least the 3 you posted. If the # of specimens increased, I am sure the max size would most likely increase as well. But it matters not, there is no such thing as a Liger, in the wild.
