I don’t suppose that this will come as a revelation to anyone, but if you haven’t seen it then this photo of a giraffe’s skeleton might be interesting. I’ve reproduced the photo twice so that you can see where I am indicating.
The pink circle shows the knee and the blue circle shows the heel. So the giraffe is really standing on tip toes. Many animals do, but the length of the giraffe’s foot is quite something, don’t you think?
And you can see how long the ‘wrist’ bones are on the front legs.
