Next up, the class of the octopus, which is Cephalopoda. Next time you see a land snail, you will now know their cousins are swimming in the murky depths of the sea. Yes, that is right, they do fall under the same phylum as mollusks like clams and mussels. The octopus species fits into the Kingdom Animalia starting from the broadest category.

Learning about octopuses not only gives you a chance to understand more about the animals that swim in the depths but also gives you the capacity to realize just how wondrous these creatures are.Īll You Should Know About Octopuses ⬇ General Categories for the Octopus Instead, it is easiest to get a basic idea of how scientists currently group them since not all octopuses look the way we imagine. To be knowledgeable about the anatomy, classification, and species within the octopus family, you don’t have to have a degree in marine biology.

There are currently more than 300 species of octopus recorded, and more get discovered every decade. They are one of the most intelligent sea creatures, filled with personality and interesting ways to survive in the dangerous depths of the ocean.Įven the most interested octopus researcher won’t be familiar with all of the octopus species living in our oceans. They each function and develop so differently, especially when comparing them to land animals. The central brain and nervous system coordination of the intelligent invertebrate is described in detail in this study.Sea creatures are some of the most wondrous animals on the planet. That is why the reference octopus has 9 brains.
#OCTOPUS HEARTS SKIN#
Their skin itself senses light and responds.įor the aforementioned reasons, it is said the eight highly flexible octopus arms (tentacles) have “minds” of their own. Like for example, they can touch, taste and also control basic motions independently. As a matter of fact, the eight octopus arms have their own sensors and controllers and can work independently without input from the brain. Notably, majority of the neurons are present in the arms of the octopus. Octopuses contain large neuron numbers comparable to those of mammals and exhibit complex behavior. However, the central brain is integrated with large optic lobes and the peripheral nervous system (PNS) of its eight arms (tentacles). Octopus has one central Brain and has evolved with large nervous systems and cognitive complexity. Octopus, an intelligent invertebrate with 8 highly flexible arms. To survive in such conditions, invertebrate Octopuses have evolved with Copper-based blood (instead of iron-based blood) called Hemocyanin, which turns its blood blue. Octopuses are deep ocean creatures, where water temperature is very low and not much oxygen is available. Notably, the systemic heart is inactive when the octopus swims – reason why it tires quickly and prefers to crawl. While the systemic heart circulates blood round the body, the two other branchial hearts pump the blood through each of its two gills. the blood formed remains inside the blood vessels. Octopus has a closed circulatory system, i.e. Not just the Giant Pacific Octopus, even an ordinary Octopus has 3 Hearts and Blue color Blood. Octopuses are fascinating, mysterious and creepy creatures of the sea. As explained below, the claim is partially hoax. In fact, the message is often shared online as an unbelievable fact. The message states the largest octopus species in the world, the Giant Pacific Octopus has 3 Hearts 9 Brains Blue Blood. The largest octopus species in the world, the giant Pacific octopus, has three hearts, nine brains, and blue blood.
