Did you know that the Red Squirrels teeth,
aren't red because the squirrel is red?
No, they are red because they are infused with high levels of iron.
That's right, you read that currently.
Squirrels teeth are literally made of steel.
The red hue you see,
are visible because the iron inside the teeth
oxidise when it comes in contact with air,
meaning they get that rusty looking colour.
