Yep, they are scary fuckers. I was a diver and instructor for many years, thousands of dives, all warm water because I am a total pansy about cold water. Actually I did some diving round Sydney and in New Zealand that was fucking cold, around 17 degrees. I hated it, a semi-dry wetsuit is fucking uncomfortable and you need to weigh yourself down with 30kg just to sink, most of my diving was without a wetsuit and no weights - I used to be fit with low body fat so I sunk easily!
Anyway,, back to the sharks.
I just looked back through my logbooks and I have dived with loads of different types of sharks Tigers, Hammerheads, White tips, Black Tips, Guitar, Whale, Nurse, Grey Reef, Caribbean Reef, Bronze Whaler (1 in the distance, fecked off quickly),Copper, Leopard, Port Jackson, Silky, Silvertips and Wobegongs, but they don't really count because they are funny cute little doodahs - the only one that ever scared me was the Oceanic White Tip, I had a feeling about that huge fucker, it was looking at my dive group in a very funny tone of voice so I got 'em all out of the water pronto. There was one other incident when some daft Dutch fucker was feeding surgeon fish with hard-boiled eggs (really stupid, I saw a fellow instructor get his hand sliced down to the bone by one of them bastards) and a big great reef shark started getting a bit uppity but that wasn't really that scary and everybody survived.
Hammerheads were my favourites, they make me laugh, especially when I got a dose of nitrogen narcosis on a deep dive and went a bit mental, more mental than usual. Whale sharks are incredible, I like them very much. I took a Belgian bloke out on his first open water dive and we saw a baby one - about 4m. He asked me afterwards if we saw them every day so I told him I had been diving for donkey's years with about 3,000 dives in my logbook and that was only he third one I had ever seen! The biggest one was about 8m and that was like the Battlestar wossisname going over.
