The octopus is considered the most intelligent of all invertebrates. A great number of scientific studies keep on proving that this is a capable creature.
They have around 300 million neurons throughout its body. They are capable of complex and flexible behavior.
They are loners.
They sometimes build lairs made of crustacean shells and other objects. They sometimes carry shell for their own protection.
When it comes to mating, males tend to keep their distance away from females. Males just send his sperm to her from distance, sometimes it comes with a gift – a severed arm from the male octopus.
Their blood is blue because it is high in copper.
An octopus can lose an arm to escape to escape a predator’s grasp and re-grow it later with no permanent damage.
Each of their arms has enough neurons to operate semi-independently.
Octopus is actually highly nutritious: A 3-ounce serving has 139 calories, 2 grams of fat, 25 grams of protein, 45% of your daily iron value, and 510% of your daily B12 value. Basically, it kicks chicken’s ass.
All octopuses are venomous, but only the small blue-ringed octopuses are known to be deadly to humans.
Octopuses have 3 hearts. Two pump blood through each of the two gills, while the third pumps blood through the body. The main heart stops beating when it is swimming, so they get tired easily. When that happens, they just walk.
Their most amazing survival technique lies in their skin. They can hide in plain sight . They can literally camouflage itself in its surroundings matching the colors, patterns, and even textures of its surroundings. Predators such as sharks, eels, and dolphins swim by without even noticing it.
Perhaps the craziest and most impressive quality of the octopus is that it can actually edit its own genes. they can alter their genetic code by editing their RNA to become more tolerant of cold temperatures, and they can improve their eyesight to see in the dark. Scientists are studying this behavior to potentially learn how to replicate this in humans as a possible cure for disease.
