"Octopuses’ brains are in their arms, which is admittedly pretty odd. Two-thirds of an octopus’ neurons reside in the long appendages that many mistakenly call “tentacles” (in modern zoology, a “tentacle” is relatively long and thin, with some kind of clubbed end). This decentralized way of thinking means that even severed arms can “think” for themselves, or at least respond to physical stimuli and try to escape whatever is trying to eat them, which is why people die from trying to swallow live octopus arms only to find that the arm is still fighting back (a reported six people die this way on average each year in South Korea, where the dish is popular).
But their peculiar approach to brains hasn’t stopped them from ranking among the most intelligent creatures that we know of. Octopuses regularly use tools, solve puzzles, and generally cause mayhem by sneaking in and out of their enclosures. They also sometimes accessorize by hopping inside old coconut shells and using them as little mobile homes, all while looking more stylish than most humans.
As they travel, they also taste everything that they walk on since their suckers are all sensory organs. You’d think that would motivate them to swim everywhere, but unfortunately one of their three hearts has to stop beating whenever they swim, which is quite tiring and means that many octopuses prefer to stroll. Their other two hearts provide blood to the gills, but that third heart circulates blood to the central organs. The main organs reside inside the octopus’ bulbous head (called a mantle), which contains no bones. The only truly hard part of an octopus is the beak, which is basically its mouth. This means that the critters can squeeze through almost any opening as long as it’s bigger than the schnoz. Everything else is negotiable.
But perhaps the weirdest thing about octopuses is that, unlike many of the other highly intelligent creatures populating our planet, they don’t live long. Some live just six months, others a few years, and most males die shortly after mating. The females last long enough to protect their clutch of eggs, during which time they slowly starve to death."

All of this and mother love as well … IMO octopus in US territorial waters should be declared Cephalopod Americans. EEO protections should be considered. "Is this a great country or what?" pl
