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.
Generally speaking, my rule of thumb is that the absolute maximum possible weight in the wild is 70% greater than the average weight of an adult male.
In other words,
The average Kodiak bear is 1,000 lbs, the absolute largest may be up to 1,700 lbs.
The average Bengal tiger is 485 lbs, the absolute maximum may be up to 825 lbs.
The average African lion is 420 lbs, the absolute biggest may be 714 lbs.
I know that a 700 pound lion or 800 pound tiger may seem like an enormous stretch, but I feel that if they still had a population of >100,000 in the wild, there would be a freak individual of that size occurring naturally. Humans have killed off the giants of these species.
