Dandelion=dent de lion="lion's tooth."

Yesterday, I was just searching for some words meanings, then suddenly looked into merriam webster dictionary and finally got this very summer word known as flower "dendelion".
And its quite interesting what I found out about it.

Behold the dandelion, a lowly plant with a kingly name.
Does the yellow flower resemble a handsome mane? Do the sharply indented leaves suggest an accompanying bite?
For the French, they did.
Dandelion comes from dent de lion, which literally means "lion's tooth."
