octopus climbing out of tanks

"Nehmo" writes:

There are mentions on the web of an octopus climbing out of a tank,
traveling across a dry surface, going into another tank, grabbing a
fish for a meal, and then returning to their home tank. Some web-
comments say there is a video that was on TV. But I haven't found
anything like it on the web. Is this behavior possible? Is this story
true?

It seems to be accepted in the literatu

Researchers and aquarists have reported octopuses escaping
captivity despite elaborate precautions (Anderson, 1997; Wood,
1994). One of the first papers was by Lee (1875), who reported
that Brighton aquarists were puzzled by disappearing lumpfish,
until one morning when the octopus was discovered in the lumpfish
tank. More recently, Boyle (1991) wrote, "Octopuses are
particularly prone to escape from aquarium tanks. Loose lids are
of little value because the octopuses will easily lift them and
push their way out of the tank" (p. 32).

Evaluation of Octopus Escape Behavior", _Journal of

I was taught the way to tell antipodeans apart was that Kiwi's put 'e'
on the end of everything and 'Strines use 'o'.

i.e. vegies vs vegos, rellies vs rellos.

Have I been lied to?

Sounds like an Aussie/Kiwi indulging in a favourite pastime of
"humouring" a Yank (taking the p... out of?).

If you want to tell them apart, hold up six fingers & ask how many
fingers - on the rare occasions you get a straight answer, if you hear
six its an Aussie, sucks its a Kiwi.

I understand what you mean by "friend of a friend". But, this was my
next door neighbor. I accompanied him to Sea World a number of times
and actually observed the tanks he was talking about. By the time I
got there, the three tanks that had Octopus in them had fully sealed
tops on them. Having talked to him and observed the site, there is no
doubt this happened.

These are very intelligent animals. I have seen an Octopus open a
glass jar with a screw on lid in order to get a shrimp that was in it.
It was amazing. The jar was filled with salt water and the shrimp
added. The lid was screwed on finger tight and the jar was then
dropped in the tank with the Octopus. The Octopus tried at first to go
through the glass to get the shrimp. Then, the animal enveloped the
entire jar with it's body and tentacles. After several minutes it
figured out how to open the jar. The entire process took about 20
minutes. The Aquarists at Sea World did all kinds of experiments to
test the intelligence of these animals.

So, yes they can move out of their tanks, explore their environment and
then return to their tanks. This is not conjecture. It is a fact.
