Fur

Otters have the densest fur of the animal kingdom.

Otters spend a large amount of time in the water, yet they still have fur.

To ensure that they stay dry they must spend a significant portion of the day grooming themselves, coating their fur in saliva.

This is possible because their fur is so dense, with around a million hairs per square inch.

A lot of species of otters were once at risk of becoming extinct due to their highly sought-after fur.

They have coarse, short fur that is yellowish tan in colour and covered in solid black spots.

Historically, cheetahs have been hunted for their fur, but today some of the biggest threats to their survival are loss of habitat, and competition for resources.

Tigers have orange fur with black stripes and a white belly.

There are white tigers that have white fur with black stripes, or that even have pure white fur.

Most Bengal tigers have orange fur.
