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.
A while ago, I took the length of the two from the picture and estimated that Amur male by isometry. From the photo, he is 1.17x longer, which equates to 1.6x in weight. Taking the 115 kg average for Amur female in STP, the estimate would be 185 kg for that male.
