Random Cephalopod Info

So on the long drive back to school from spring break, I learned several really cool things about the octopus and the giant squid. For example:
octopi are very intelligent

          - you can train one to unscrew a jar

          -you can train one to open a lock with a key

          -you can put a lock in the tank, give the octopus a key in a closed jar and have it open the jar, take the key and unlock the lock.

unfortunately, i couldn't find any lock videos.

also, concerning giant squid:
scientists know very little about giant squids because once they catch them, no matter how similar to its original environment it's kept in, the squid will die almost immediately. so they dont know if/where they congregate, where their breeding grounds are, what their habits are, etc. they're not even positive why they die once captured.
