Click here for a 40 second Outrageous Octopus Attack Scene taken from the movie, The Right Nut.

Fun Facts:

Though octopuses can be hard to keep in captivity, some people keep them as pets. Octopuses often escape even from supposedly secure tanks, due to their intelligence and problem solving skills. Octopuses are also quite strong for their size. Octopuses kept as pets have been known to open the covers of their aquariums and survive for a time in the air in order to get to a nearby feeder tank and gorge themselves on the fish there. They have also been known to catch and kill some species of sharks.
 

Weird Stuff:
A common belief is that when stressed, an octopus may begin to eat itself. However, limited research conducted in this area has revealed that the cause of this abnormal behavior may be a virus that attacks the octopus's nervous system. Thus this behavior may be more correctly labeled as a mental disease.
