Octopus Sans Garden

There has been some interest in octopuses (I, being a heathen, used to call them octopi–sorry!). Nevertheless, I’ve always found them fascinating.

Years ago, I was able to successfully maintain a marine (saltwater) aquarium. At various times, I had coral and clown fish, sea horses, and an octopus, although not all at once. The octopus was the most interesting–here’s what the octopus taught me.

  • My octopus could not only change colors for camouflage, it could mimic patterns and shapes. On the bottom of the aquarium, it would match the pattern and color of the gravel. On coral, it would have the color of the coral and appendages on the skin that made it blend in marvelously.
  • They are so good at camouflage that there have been reports of apparently empty aquariums being drained, only to find a number of octopuses hiding.
  • An octopus is curious and loves to climb. If one is in an aquarium and there’s a teeny-tiny-miniscule gap, the octopus is likely to squeeze through and climb up (Apparently,up is their favorite direction),
  • When my octopus saw food, it turned reddish–it’s “Time to Eat” signal.
  • My octopus–like all other octopuses–had no bones. It was a squishy organism. It’s hard to believe that the favorite food for an octopus is crab. It amazes me that the squishy creature routinely eats a one with a shell and nasty pincers.
    The octopus would stalk the crab, then suddenly turn red and in a split second, attack land on the crab like a parachute. An expels a toxin that paralyzes the crab and in the middle of the octopus underside is a very effective beak–exquisitely designed for opening a crab shell.
  • Octopuses are wonderfully intelligent, although difficult to keep in captivity.
  • My octopus would watch me as I walked around the room. It used two of its arms to hold onto the aquarium glass. When I walked, it would move along in parallel and in synch with me, supporting itself with two arms and swinging the others to imitate my legs.

Now, isn’t that better than reading the news?
