Amur Tigers

[Sabre]

GrizzlyClaw. Pckts. How do you know we have a captive Siberian tiger from the Manchuria? So far I know is that majority captive Siberian tigers are from the Russian Far East from past. If there is captive Siberian tiger from the Manchuira, then I am definitely sure we do have a captive bengal tiger from northern indai, nepal, bhutan. Plus, the manchurian tiger is already wiped out like 50~60 years ago unlike northern bengal tiger. Siberian tiger from Russian Far east still can be huge size long as they feed sufficiently.

Sorry for you, but I am not telling my location xD I had a stalker back in 2012. I am not telling my location and placed where I worked. Plus, I mainly dealt with smaller tropical birds and bird of prey. But I knew keepers dealing with tiger. My zoo don't have the siberian and bengal tiger anymore. We are mainly breeding endangered sumatran tiger and malayan tiger. I've been in zoos in Korea and worked in zoo in America before(I quit because I hated it). The description page of the Siberian tiger is always mentioning that Siberian is the largest subspecies of the tiger(American, European, and Asian zoos). And Siberian tiger looks bigger than bengal in general. I don't know how to post photos in here though. Siberian tigers are in Korea are definitely heavier and bigger than bengal tigers are in Korea(which they are from all part of India like north and south).

About here, "And lastly, if we are saying the Manchuria Gene or lets call it the "giant amur gene" is gone and only used in captivity which does allegedly produce the largest Captive Cats than we must only compare the N. Indian Tiger gene as well."
If you study genetic and genomics. Size and gene doesn't work like that at all. If southern bengal tiger have higher prey base, better nutrition, and feed sufficiently. Then they can grow bigger than northern bengal tiger who didn't feed well and low prey base. I've seen one hunted 11ft southern bengal tiger photo from 100 years ago.
I have a friend over 2m tall, but his sister is only like 150cm. But her mom is 180cm and her dad is like 178cm tall. My other friend is 193cm tall, his dad is like 191cm, his mom is 160cm, and his 2 sisters are like 160cm and 175cm. Same as for the tiger, northern and southern mix breed bengal tiger still can grow big as northern bengal tiger or small as sundarbans tiger.
As stated in bergmann rule, animals are living in colder environment is generally larger than warmer environemnt for mammals and birds. About body fat, I read article 10 years ago that Siberian tiger only has 5 cm body fats under their belly due to colder climates they are living in. Their overall body fats are similar as other tiger subspecies(beside belly). Plus, they have a long fur to prevent from coldness along with body fat.
Main sad fact is that the Siberian tiger habitat prey base is extremely low since end of 1990s. The prey base in Russia is not abundant enough for those tigers to realize their full potential(weight and robust). Prey is more scattered and the Russian tigers need huge territories to capture sufficient food, so much more energy is expended in the food quest. Reply
