I first fell in love with octopuses when i was participating in a behind-the-scenes tour of the Ripleys Aquarium in Myrtle Beach. When I found out the big crate of toys that I saw were for the octopus because they are brilliant, i was hooked. I have been fascinated and such an admirer of these amazing creatures since. These are just a few of the reasons...
They aren’t called ‘Tentacles’, they’re called ‘Arms.’ Tentacles are reserved for squid, cuttlefish and nautiluses. Octopuses have eight arms, zero tentacles.
Octopuses are widely considered to be the most intelligent of all invertebrates. Scientists say octopuses are capable of learning from experience and maintaining short- and long-term memory. They’ve also been observed using tools in an intelligent manner.
Each Arm has a mind of its own…literally. Some two-thirds of an octopus’s neurons reside in its arms, meaning they can react to stimuli and function at a fairly high level on their own, even when severed from the body.
Compared with octopuses living in tanks full of interesting decor like shells and flowerpots, octopuses living in captivity in more spartan conditions become pretty stressed out. Some even turn to a disturbing behavior known as autophagy, or eating their own appendages, in such non-stimulating environments.
Octopuses have NINE brains. One central brain controls the nervous system. In addition, there is a small brain in each of their eight arms — a cluster of nerve cells that biologists say controls movement. This allows the arms to work independently of each other, yet together toward the same goal.
Scientists recently found that octopus skin contains the same light-sensitive proteins present in octopus eyes, meaning an octopus’s skin can sense and respond to light without information from the eyes or brain.
A common octopus has about 240 suckers on each limb, and a particularly large sucker can hold up to 35 lbs. The suckers are also extremely sensitive; they can pick up subtle chemical signals and move individually, even folding in half in a pinching gesture.
Like chimpanzees, dolphins and crows, octopuses are among the special set of intelligent animals that have been observed using tools.
Octopuses have three hearts. Two hearts pump blood to the gills. A larger heart that circulates blood to the rest of the body.
Octopuses are masters of camouflage. An octopus can change the color of its entire body in just three-tenths of a second. But it doesn't simply take on the general pattern of its surroundings. Instead, it often mimics specific undersea objects, like plants or rocks, to disappear into the underwater scenery.
Octopuses or even Octopode is a correct plural of octopus…Octopi is NOT.
‘Octopus’ hails from ancient Greek.
Octopi “has no etymological basis.” It only exists due to a modern fallacy that octopus comes from Latin. Its actual origin is the Greek word oktopous, which literally means “eight-footed.”
