The octopus is one of the most fascinating animals due to its peculiar characteristics, having great dexterity and intelligence.

This marine animal is a mollusk that is capable of transporting materials to build its shelters to have a better chance of survival. With its 500 million neurons, it has an important learning capacity, managing to solve complex problems by using observation as a method. They have three hearts with specific functions: two of them to move the blood past the gills and the other to ensure that it continues the circulation to the rest of their organs. His blue blood because he must develop it from copper to survive at the bottom of the oceans; that is, they have hemocyanin, which makes it easier for them to transport oxygen if the water temperature is very low. Octopuses only reproduce once in their life, so most females die while laying their eggs and males after having fertilized them. This leaves the young on their own. A peculiar characteristic is that, when they feel threatened, they can launch a jet of ink that helps them to mislead their attacker and escape. One of its compounds is tyrosinase and it has toxic properties.

Octopuses can contract some muscles to change shape and blend in with their surroundings. For this they also use the voluntary color change, which can make them invisible; Or if it is the opposite and they want to capture the attention of the female, they can perform courtship rituals with body movements.
