First time video of the unfortunate "dirty white" tiger cub

We have discussed the animal pictured above in past threads, and below is a refresher:

CHENNAI: One of the three ‘white’ tigers born in Vandalur zoo in June seems to have changed its colours — most of its body and legs are now black.

The black cub, along with its completely white siblings, was on display for the public to see for the first time at the Arignar Anna Zoological Park in Vandalur on Sunday, and drew hordes of excited visitors.

A black tiger is something of a rarity and zoo officials are quite excited by the development. “The colouring might be due to genetic reasons. A black cub is exactly the same as a regular tiger in all aspects, except for its skin colour,” said zoo director KSSVP Reddy, who is also chief conservator of forests.

Reddy ruled out the possibility of inbreeding as the reason for the unusual colouring. “Inbreeding occurs only over generations. The mother, white tigress Anu, has only given birth twice,” he said.

Zoo biologists said the large presence of the pigment melanin in the cub was probably the reason for 80% of its skin being black. The skin colour of tigers is determined by the presence of black and yellow pigments. In most tigers, the colour yellow dominates over black to give them their characteristic colouring.

“In this cub, the reverse has happened — black is the dominant colour,” said senior zoo biologist Dr Manimozhi. “We are monitoring the cub. The skin colour that he grows into when he reaches adulthood will be the permanent one,” he said. It is the dominance of yellow pigment that enables tigers to survive in the wild for long, he added. “In fact, this is the reason why most white tigers are found only in zoos and not in the wild,” Manimozhi said.

The birth of the three cubs on June 6 has taken the tiger population in the zoo to 15. Zookeepers said the cubs, which weigh about eight kg each, are active and healthy. They are given a regular diet of chicken and beef.

Wade,

I don't believe in fortune tellers, but I predict that tiger will grow to be one the most beautiful animals anyone has ever seen. I cant wait to see this cat mature in the coming years.

"Unfortunate dirty white tiger cub" ha ha. he'll never sit at the "back of the cage"

Vincent,
I'll bet you a fin, that what you see today, is what you will see 5 years from now. In the color breeding of horses, particularly Appaloosa's varnish/frost is the least popular color. It just isn't pretty. I don't believe this cub will change from what it is now. As pictures of it at a week old to today show no change. It is just a "fluke" I feel similar to a King Cheetah. FYI here is what occurs with an Appaloosa horse:

Appaloosa varnish is a progressive silvering effect that leaves colour (called varnish marks) on the bony prominences of the face, lower neck, forearm, knees, hips and stifle. It is caused by the SvS allele. This is probably semi-dominant. It’s thought that horses homozygous for the allele become lighter than heterozygotes.

The pattern is sometimes called marble, marble roan or varnish roan. However the pattern is not roan and, much like with gray horses varnish horses are born another color (often with another appaloosa pattern), with just some varnish on the head, and the silvering develops with age. Unlike with gray other appaloosa spots usually retain pigment. The silvering can occur over the entire body or just over the rumps, when it may be mistaken for frost, though it is actually a varnish blanket.

Now a pure black tiger, with stripes, as a tiger is supposed to have, that would be the real deal. I hold my breath it is out there somewhere, in my lifetime, and as soon as Ian arranges financing through his "connections" I am going to look for it. I'll take pictures and video, but I am sure not bringing it back, so that it can suffer the same disrespect and irreverence that the Rewa White Tigers did. While I am there, I am going to check on that new snub nosed monkey, and see what is up with his breathing problems. We all have dreams, don't we Vincent.

I'll bite and take that bet, the little guy is stunning to my eyes already. No change needed.

Check your facebook messages, you don't have to hold your breath anymore for that Black Tiger.
