Octopus is a soft-bodied sea creature (cephalopod) with tentacles that extends out. When the octopus moves around the coral reefs and the seabed, it looks like a giant “hand” sweeping the ocean floor. It’s a cute creature that surprises all of us with its amazing biology and abilities.

Octopus is the most intelligent of all invertebrates.

Intelligence in invertebrates means the process of acquiring, storing in memory, retrieving, combining, comparing and using context information and conceptual skills. — Wikipedia

Octopus is the most intelligent of all invertebrates. Scientists who studied the Octopus found that that it can work through mazes, open jars, and learn new skills. Octopus adapts to its surroundings by changing camoflouge readily; changing the way it handles its prey depending on the species and changing the way that it passes through water depending on whether predators are present.

The Octopus brain starts at its bunch of paired ganglia and distributes all along the octopus’s tentacles. It’s a perfect “distributed” model of intelligence. Scientists study the octopus to understand this intelligence mechanism to use it to create the soft robotic arms.

Octopus have three hearts. It has one systematic heart that circulates body around two branchial hearts. The systematic heart is inactive when the animal is swimming. The blood of an octopus is blue and contains the copper-rich protein haemocyanin to transport oxygen. Haemocyanin dissolved in plasma and gives the blood the blue color.
