Today’s interesting fact has to do with Thumbs.

Specifically with how many distal digits animals have.

There are two types of animals that normally have 6 digits on the ends of their forearms.

The Giant Panda is one and moles are the other.

Both have a 'second thumb'.

In the case of the Giant Panda, the first thumb is like a finger and the thumb is a growth developed from one of the wrist bones.

In the case of moles, the second thumb has also developed from of the wrist bones.

This second digit is not the same as the polydactyl condition that sometimes occurs in cats, as only some cats have multiple digits, whereas all Giant Pandas and Moles have these second thumbs.
