People Are Just Realising Where Penguins' Knees Are, And I Wasn't Expecting That

If you’re anything like me, you probably never knew penguins had any knees at all.

Well, they do ― as author and medical historian Dr. Lindsey Fitzharris shared on X (formerly Twitter) recently.

She posted an x-ray of the bird on her page with his knees located more or less directly below the ribs ― far from the bird’s visible legs. 

“Wait... so mean to tell me these guys go all over the place... in a sort of squatting walk?” one X user responded to the news.

Happy Tuesday!
