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.
In the Amur post, I did not bother postng the chest diameter but I'll go back and post it later.
Top photo:
Without correcting anything for perspective:
The male is 1.08x the length of the female but the male is at a shortening angle.
His chest diameter is 1.41x that of the female's, however.
Bottom photo:
Male's length in this one is 1.40x the female's, but the female is at a shortening angle.
Male's chest girth is 1.37x that of the female's.
Not exactly sure how much to compensate for the male being closer in the photo. Perhaps the male is 1.10x the female's length (average the two photos and deduct for his positioning) and the his girth is 1.25x the female's with the same compensations.
So say the female is 130 kg, isometry results in:
Length based: 1.10^3 * 130 kg = 173 kg
Chest diameter: 1.25^3 * 130 kg = 254 kg
Avg. = 214 kg
If I compensated the male too much, we could say 1.15x length (198 kg) and 1.3x girth (286 kg) at best, which using the above method would come to 242 kg. I'd put this number as the high end and would prefer the more conservative numbers above. All in all, the male is stockier than the female but not much longer.
