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.

You are right in one point, cheeking again the document of Yamaguchi, the average for male lions at species level is of c.175 kg and for females c.120 kg. The weight for male tigers, at species level, is of c.160 kg and for females c.115 kg (Yamaguchi et al., 2009). Still, in any of the two document of Yamaguchi, about this point, is showed which were his sources, so we can only "guess" which data was used by him, although Peter and I have found similar results with our own data.
However, the average of 180 kg for Serengeti males is incorrect, the data show that a little over 170 kg is the correct figure and according with Dr Packer could be even lower in some areas.
There is no "educated guess" on Crater lions right now, as the result of the formula in that old document (212 kg) is incorrect because the formula itself was proved incorrect, so why we most quote something that is not correct? Yamaguchi & Haddane (2002) estimate them at "over 200 kg" and Dr Packer estimated a gain of 10-20% over the average Serengeti specimens based in chest girths, but those measurements are no different than those of the Southern area (which can be up to 139 cm), so the best guess would be that while East African lions average c.174 kg overall, the Crater lions, been larger, average like the southern populations, which are know the weight 190 - 202 kg on average.
