just reading about guy having closeup with big shark off Esperance and this is something Ive been thinking about for a long time, mind you never done any research on it.

Why do the majority of surfers, divers etc wear black suits?
dont they look more like seals etc?
Do sharks have colour sensitivity?
Would bright coloured wet suits be a deterant to sharks?
Or is it all based on the splashing of feet and arms of freaked out humans?

Many many years ago in Adelaide I went swimming on my own around midnight off Glenelg, I knew I had consumed too much booze and was in trouble swimming out to far. Now was it a dolphin that pushed me or was it something else that brushed by me..... either way it put me off swimming out deep ever since. Living in Pt Lincoln and being in my 60's I tried going shark cage diving a year ago to try overcoming the fear but messed my bathers.
