Why are all tongues pink ?

Just wondering , anyway with answers?>:o

My dog’s tounge is black, but then she’s a chow chow.


One of my dogs has an interesting tongue.

The top is pink with blue spots, and the bottom is blue with pink spots.

He’s part chow.

Mainly talking about humans , like whites have a pink tougne , blacks have a pink tongue , i have a pink tongue why doesnt the colour vary a lot about humans

It’s because we all have red blood.

Since your tongue doesn’t get much exposure to sunlight it doesn’t need melanin to protect it from ultraviolet rays. Same reason everybody has the same color internal organs … .

And the same color teeth. :rolleyes:

Put it this way, when was the last time your tongue got sunburnt?
