Polar bear is protected by by the thick fur and has black skin to absorb the heat
Will you accept an extinct animal? If so, I nominate the Chalicothere.
Koalas have opposable fingers and their paws are specially adapted to grip tree branches. Female koalas have pouches in which they carry their babies and they have tough skin on the bottom of their feet to help with traction on tree branches.
No all primates have fingers.
It doesn't, unless an animal has permanently lost its 'fingers' or 'paws' or 'talons' etc, (which me may essential in the animals' life) than the number of fingers an animal has does not concern its survival
Monkey
The animal with a tongue so long that it is anchored to its sternum is the giraffe. This adaptation allows giraffes to reach high leaves and branches in trees while feeding. Their tongues can be up to 20 inches long and are prehensile, aiding in grasping foliage. This unique feature is essential for their survival in their natural habitat.
It varies from animal to animal. For example a camel's climate is much more hotter than of polar bear's climate
Animals do not have fingers. If you mean claws, probably the mouse.
I think the answer to it is a sloth.

Animal scales are for protecting it from stuff like preditors or branches/twigs
