Ever since I was young, frogs have been one of my favourite animals. and a few years ago I even had a young frog in my room for a short while to study it, which I kept in an old fish tank. You can read about that here. I've always thought that frogs are cool with the way they have adapted to jump and swim.
The day after I appeared on The One Show, I received a kind email from a man called Mr Lydamore asking me if I would like a frog skeleton.It had been in his family for a long time after he found it under a cooker - he doesn't know how long it was there, but it could have been decades. It was a very kind offer ! This is what I've learned from it:
This is the front right leg. The humerus has lots of area for muscle attachments, and the radius and ulna, which are two separate bones in the forearm of humans, are fused together here. That gives less flexibility in the wrist area, but greater strength. It's amazing to see the finger bones (phlanges) and how the front hands face into the middle of the body.
This is the back foot. The length and shape of the toes has a big impact on how the frog moves. Tree frogs use them to grip round branches. All frogs toes and fingers are webbed to help them swim.
Its tibia and fibula are fused ( just like the radius and ulna ) The leg bones are longer than usual to help muscle attachment, which leads to them jump higher and swimming faster.
