As I tried to imply earlier, they actually are rather wary of things they're not sure of. It's when they are sure, but wrong, that we have problems.

According to a BBC (David Attenborough) programme on sharks from a few years ago, they are brighter than you think. Some stats for you...
1/ They can identify a single drop of blood in 25 million drops of seawater
2/ Can detect low frequency sound from more than a mile away
3/ Sharks have a line of pressure sensors down each flank for a 3D map of their surroundings
4/ Eyes are 10x more sensitive than ours in low light
5/ Can detect electrical impulses down to 5 billionth of a volt

And you can roll your tongue!

None of the stats listed refer to Intelligence or ability to Reason. Sharks are an extremely well tuned killing machine, but they're as thick as brick. If if helps, trying thinking of them as a Microsoft clone of the iDolphin

This is a great movie that shows the "Landlord" is not an indiscriminate killing machine. It is filmed at a place, that is now a National Marine Sanctuary, called the Farallon Islands. It holds an incredible amount of life, and although I haven't had a chance to dive there yet it is supposed absolutely incredible diving. It is one of three hot spots in Northern California for Great White sharks. They do cage diving there, but you can't chum anymore, so it is miss more than hit.

Great video Peter.

That's a very thought provoking video. He has a very unusual but intimate relationship with the sea. It reminds me a little of this:

The Absurdities of Life. - YouTube

That's a fantastic story, I like the bit were he says "So I sold the house, and kept the boat" Brilliant!! which in many ways reminds me of this one.

Found another video, this time of a great white biting the pontoons of a RIB.

Unbelievable.

I have the honour of counting Frank as a good friend. He is exactly as the film portrays him. He lives on the RIB 24/7/365. I help him with the maintenance of the RIB, which has a hard life as it is never off the water, other than for annual maintenance.
He has an endless list of funny incidents and anecdotes that he has witnessed over the years and has started putting them down in a paperback form that is now on sale on Amazon. The confessions of Hayling Rescue.

All profits go towards maintaining the RIB. There is also a Friends of Hayling Rescue Facebook page.
