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.

Based on the regression equation used, mean chest circumference of lions from Ngorongoro Crater is 126.3 - 127.7 cm (n = 6-12+) and up to 131 cm (n = 12). 131 cm is based on the assumption that larger lions aren't already included in the 1991 research study, and is not the proper result as it is based on larger individual lions. Hence the proper value will be lesser than 130 cm. This is negligibly larger than lions from other region (difference of only 1-3 cm).
I think that 127 cm is a reliable average for the chest girth of male lions in Ngorongoro.
