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.
450 kg does seem a bit high. Though one thing using length has going for it is the nice sample size, giving it more power. The Copenhagen specimens are awkward to use as for one, they're weights of specimens after death, thus likely not a prime animal. The sources of the specimens aren't from top programs either, and cats, especially tigers, seem very lanky in captivity. I believe Peter touched on this in light of their instincts and necessities in the wild. Still lots of testing to do. I'm trying this with wild lions, but their correlation is abysmal. It's positive, but the data points aren't so nicely fit as the tiger data.
Right now, I'm thinking 450 kg is a freak Ngandong tiger while 409 kg is a big male, but plenty of more work to do.
