Each Octopus Arm Moves as if it Has its Own Brain

Each Octopus Arm Moves as if it Has its Own Brain

What does it take to enable an octopus to use all eight arms efficiently? Each arm may be in contact with a different substance, and they are soft and pliable, so they can bend and twist in response to whatever stimuli they receive. As a result, each octopus arm moves as if it has its own brain.

Researchers recently discovered that the arms gather data and move independently or with other arms without consulting the octopus’s brain. The octopus has a central brain connected to a nerve ring that connects to each arm. In addition to the arms’ connections to the brain, a nerve connects each arm to another, located two arms away. This arrangement allows each arm to communicate directly with others and with the central brain. The arm’s connections to other arms allow rapid communication to function quickly and efficiently.

Researchers are still studying how the octopus puts all this together to move eight arms in a well-coordinated way. Roger Hanlon, a researcher with the Marine Biological Laboratory, said, “We are in that intriguing ‘mild state of confusion’ that is simultaneously perplexing and exhilarating when unexpected discoveries are revealed.”

God’s design of every form of life is amazing and offers much for science to study and learn. Our understanding of how nerves function and how the brain interprets the signals it receives from the nerves is still in a primitive stage. However, we know that each octopus arm moves as if it has its own brain, making the octopus a very complex and intelligent animal. We see God’s wisdom and creative ability displayed in every form of life.

Intelligent Alien

Octopus - Intelligent Alien
Science fiction writers and UFO proponents like to propose strange looking aliens that can do incredible feats. The common octopus is a beautifully designed and incredibly intelligent animal that could compare to any intelligent alien of science fiction.

The octopus has no bones in its body, in fact, the only hard part of an octopus is its beak. That means that the octopus can take any shape and fit through almost any opening. One famous example is an octopus that escaped from an aquarium in New Zealand. That animal picked apart the lid on its aquarium, crawled out, went across the room and down through a drain hole that led to the sea and has never been seen again.

Octopus arms are muscular, boneless, and lined with suckers that are covered with chemoreceptors similar to our own taste buds. An octopus can taste everything it touches. They live in oceans around the world from equatorial waters to Antarctica and the Gulf of Alaska and from deep-water trenches to shallow reefs.

The arms are also filled with neurons, so the brain cells of an octopus are in its arms and not its dome. The octopus has sacs of pigments which are controlled by the muscles. It can release this “ink” as a defense mechanism. Its arms also have cells that reflect and scatter light. That means an octopus can control what it looks like. It can resemble a sea snake, a fish, anemones, jellyfish, sand, or seaweed. It’s a master of disguise. In addition to the right color and form some octopus species copy the movements of whatever animal they imitate. The camouflage does not seem to be accidental but is controlled by the octopus itself.

For a soft-bodied animal to survive in the ocean, some unique characteristics must be designed into its DNA. We think the number of features the octopus has is astounding. To have one unique characteristic might be possible–produced by a mutation and supported by natural selection. To have all of the abilities of an octopus would not happen by one mutation. Fossil evidence indicates that octopuses have been around throughout the history of the oceans. They even predate the dinosaurs.

Octopuses resemble an intelligent alien, and they certainly make E.T. look like nothing special. They give evidence of the Designer of life.

The “Aliens” Among Us

Octopus
Octopus

Imagine a creature that has no backbone, no ribs, in fact, no skeletal structure at all. It can weigh up to 200 pounds (90 kg), and its arms can be almost seven feet (2 m) long. It has three hearts, and the color of its blood is blue. Its limbs are covered with hundreds of tongues which have taste receptors, and its body is embedded with cells that sense light. Its eight arms are covered with suckers that can be moved independently and have tongues and taste receptors embedded in them. This “alien” creature is not as alien as you might think. It’s the octopus.

The octopus is the dominant member of a class of marine animals called cephalopods which number some 750 known living species. Octopuses have about 300 species, and they are far and away the most intelligent of the cephalopods. Trying to keep an octopus in an aquarium is almost impossible because they always find ways to escape. Since they have no skeletal structure, they can squeeze through the smallest crack. They can unscrew a jar lid, fit into a drain pipe, and camouflage their activity by releasing a cloud of ink. In an article on “Animal Intelligence” in the “News and Notes” section of our November/December 2016 printed publication, we told the story of “Inky” the octopus. Inky squeezed through a narrow gap at the top of his tank at the National Aquarium of New Zealand. After flopping to the floor, Inky scooted across the room to the opening of a drain pipe. He got into the pipe and dropped 164 feet (50 m) to where the pipe entered the sea, and there he escaped.

Octopuses are designed to control various animal populations in the coral reefs and other areas of the oceans. They are beautiful creatures that are part of God’s design for an ocean environment that humans are only beginning to understand.
