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 am not sure of how well lions' smelling organ works, I am sure it is works incredibly well, but their memories are something very different. In dogs, for instance, their short term memory (their functioning memory, the thing that keeps them on the task at hand) is around 3 seconds, meaning if you are going to correct your dog, you have three seconds to do it in, or else they will not know what they are being corrected for. That is one reason dogs are so easily distracted, and rarely ever go back to the task they were doing when they got distracted, such as playing with a toy, get distracted by something, and they don't return to the toy. How long the memory of a lion is, both short term and long term memory, is something I am not sure anyone really knows.
