Things to know about the giant Pacific octopus, which is naturally found in the waters of the U.S. West coast, the Aleutian Islands and Japan: A central brain controls the nervous system. The way that the neurons are distributed throughout the arm from the ganglia not only allows each arm to process sensory input individually but also amplifies what they sense. However, unlike other creatures, not all of its neurons are located in its brain. I guess you could say octopuses are always thinking on their feet! Octopuses' Big Brains And Unique Behavior Spur Basic Research : Shots - Health News Move over, fruit flies, rats and zebrafish.

Octopus brains are also larger than other vertebrate species, although they are not larger than mammal’s brains. Octopuses are equally as strange as they are impressive. Yes, when you hear claims that an octopus can taste with its arms, it’s true. They have a sac where the ink is produced when they need to release it and escape from danger. Using eight arms that all move independently requires a lot of coordination- and brain power. Imagine if your brain did not have to handle menial tasks such as processing raw sensory data or keeping you coordinated. An octopus has three hearts, nine brains, and blue blood. The giant Pacific octopus has three hearts, nine brains and blue blood, making reality stranger than fiction. In fact, octopus brains are actually disc or doughnut shaped.

Not only that, but make it into neighboring enclosures where they devour the neighboring fish in other tanks. As an Amazon Associate I earn from qualifying purchases. Vertebrate brains all have a common architecture. When cephalopods are compared with mammals, the lack of any common anatomy only increases the difficulties. They can complete puzzles, untie knots, open jars and toddler proof cases, and are expert escape artists from aquariums. However, in its structure, it differs significantly from the vertebrate brain, but that does not interfere with its efficient use. Not only that, but octopuses actually have more than one brain! So this means each arm got an individual brain and the last one stays in the head. The arms of the octopus are not only sensitive to touch and temperature but they can also detect changes in light, color and taste. Octopi Have a Brain In Every Tentacle! Two of the hearts work exclusively to move blood beyond the animal’s … Octopuses have three hearts. Research has found that magnesium can support healthy brain activity, memory, and learning processes. So what is considered “intelligence” for animals, is likely wildly different than human intelligence. Octopuses essentially have a brain at the base of each arm which are connected to a larger, central brain. The nervous system of cephalopods is the most complex of all invertebrates. What? Octopus contains magnesium — a mineral many people don’t get enough of in their diet. It’s not super surprising though when you consider the fact that octopuses have not just one, but nine brains! Comparing octopus brains to all chordate brains: Different animals are good at different things, as makes sense given the different lives they live. This allows them to take advantage of their highly developed and advanced eye structure. Octopuses have 9 brains because, in addition to the central brain, each of 8 arms has a mini-brain that allows it to move independently. Also, when precise coordination in arm movements is required, the ganglia can communicate and coordinate with each other without having to go through the main brain. The Octopoda consists of around 300 known species and were historically divided into two suborders, the Incirrina and the Cirrina. Most of the time, marine mammals get all the recognition for being the brains of the sea, but octopuses and their relatives- the cephalopods are super smart!
