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 lot of the weights posted in YouTube animal channels come directly from this forum. That channel specifically is not reliable as the person who runs it is extremely bias, similar to what you see on some Tapatalk forums.
That same individual posted a comparison between an Ussuri brown bear and a Siberian tiger stating that the tiger was 200+ kg on average, when we know that's far from the truth. The purpose was to decrease the size of the bear and increase the size of the tiger to make them as similar in build as possible.
I'd stay away from those channels/forums and treat all the "data" they post with a grain of salt.
