Wow... he was huge... and old. It's a shame to kill him really.... He's like the big old fish in "On Golden Pond"... He's gotten so big it'd be a shame to kill him. He'd have been a great sight at a zoo... and perhaps we could have learned exactly how long he could have lived.
How big do these animals get?
I agree. On the other hand, I have no idea how you'd capture a beast that size. I'll tell you one thing, though, a zoo would have paid enough for one that size to make it worth a try. I'll bet Steve Irwin gets sick to his stomach when he reads this story. Seriously, that guy really loves these things.
