I'm feeling quite gutted about this. It really was a horrible accident, at least if it had been a crocodile you could say it was his fault - last I heard he was swimming along the bottom of the sea and must have brushed over the top of the ray. It would have been hidden, there would have been no way of seeing it.
It's easy to say he put himself into danger but I think he was an extremely talented and intelligent man. If he wasn't, he would have died a long time ago the first time he picked up a snake.
As for the baby incident, he felt there was no danger or he wouldn't have put his month old son into that situation. It's a different culture & he would have done it whether or not the cameras had been there, as his father did to him. He grew up around crocodiles and felt it necessary to bring up his son in a similar way to how he was brought up.
I think it's really sad for the family he leaves behind, but teh same could be said for any father who dies in a tragic accident, no matter what his job.
