Ping frames

[Pogasu]

I've got a question: Im using Ethereal to see my network activity and to try it, I ping from one computer to another one. My ping data size is 2000 bytes but I see that the frames containing the ping request and reply have only 562 bytes. Why is that?

Ethereal shows this:

Thanks in advance!

It's not really something ive concerned myself with too much but perhaps it is something to do with MTU's
