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.

The Black bear is too distantly related to the Brown bear within the same genus.
Like lion and tiger, they can produce the unhealthy and mostly sterile offspring like the liger.
However, the two Black bear species can successfully breed with each other and produce the healthy fertile offspring.
