Uncle Pug once bubbled... I have Realplayer 7 but none of the videos will download for me...
Perhaps you folks could just explain what is happening in the video with the shark and the octopus.
They moved a giant octopus into a tank containing several sharks. They felt that it due to it's size and camouflage ability it would be okay in the tank with them.
After a while, the carcass of 3-4 foot sharks started appearing on the bottom.
They set up cameras to find out what was happening.
Showed the octo moving along the bottom hiding itelf. Then a shark cruised by just above it and WHAM! the octo wrapped its tentacles around it. Looked like a boa strangling it's prey...
In the blink of an eye, tentacles flashed out of a crevice and encircled an unsuspecting shark cruising along. That 4ft shark was engulfed by Octo! None of the typical spinning action of the shark...the Octo had him grabbed and pinned fair and square and was dragging him into the lair.
They never said if the shark carcasses they had been finding had been eaten on or just killed. The big surprise was the apex preditor being killed by an invertebrate.
I recall reading a book called the Pearl Fishermen. A swedish guy who went all over the South Pacific in the 1930's. There's a part where some tribe in the Polynesian Islands ( I think! ) catch a shark and a octupus and put them in a small enclosed lagoon to fight each other. The octupus win.
