Ermm.. no... cant say I have.

Yes - we have an octopus as a house pet. He spends about an hour most days out of the tank.

Nope, sure havent, ever. I hope this helps! ☺

1) I don't know how they got the idea for this: "A hockey puck sliding northward at 6.0 m/sec on smooth ice collides with an octopus sliding eastward. After colliding they slide together in a direction 37 degrees north from east. The octopus is twice as massive as the puck. a. Sketch a vector diagram showing how the final momentum is related to the two original momentums. Let "north" be toward the top of your paper. Label the puck's original momentum with a "P", the octopus' original momentum "O", and the final momentum of the combined puck and octopus "F". (skills 9, 11, 16) b. Use your knowledge of triangles to determine the ratio of the octopus's original momentum to the puck’s original momentum. (skill 10) c. Use the given data with the ratio in 4b to calculate the original speed of the octopus."

Several weeks into the exhibit, staff noticed that fish were beginning to vanish from nearby tanks, confounding the aquarium security. After some time a night janitor noticed an octopus climbing its tank, sliding across the floor, sallying up and into a nearby tank, killing a fish, and returning home."

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."
