Last night I was having a few frosties with one of my crazy dive captain friends. On tuesday he speared a huge grouper which bled out very quickly and before he could bag it two very large sand tigers came out of nowhere and were fighting over it big time . The water was very clear and as he slowly came up he could see big sharks coming up also so he released his other fish bag and one came from behind his tank and under his arm and grabbed it from behind with one gulp. This guy has been bit before by sharks and eels and it usually has to do with food etc and pretty much his fault. I find it amazing that there are not more shark attacks. If it were me I would of released my patented brown anti shark fluid and they would of never seen me...Frank
