- FAQ: Do penguins have knees? -

Looking at a penguin standing or waddling around on the island it may look
like they have very short legs and no knees.



But yes, penguins do have knees!

A penguin’s leg is composed of a short femur, knee, tibia and fibula. The
upper leg bones are not visible as they are covered in feathers giving
penguins a very short legged appearance. Here you can compare the leg of a
penguin skeleton to a model of a human skeleton.





Take at look at these x-rays of one of our penguins and you can see the leg
bones, including the knee joint and how most of it is covered in the
penguin’s body.
