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.
I won't lie, I don't see much difference in the body, but in the tail, Tilikum is thicker or fatter than the ones Guate posted (but similar to the latter orca in my earlier post), however one would put it. I know in a lot of land animals a fat tail indicates an overweight animal.
On the growth curve, it looks like orcas never stop growing, or are at least growing significantly well into their twenties. That'll make it difficult to put an exact cap on their size.
