The Crocodile Hunter was killed by a Sting-Ray this morning.  Irwin was a great entertainer and a great teacher.  He took the camera into the animals habitat and gave his viewers a perspective of the animals not often shown.  To appreciate something, you need to understand it.  Steve Irwin encouraged people to appreciate animals by helping them understand them  My sincerest condolences to his family.  May he rest in peace.
