Hello everyone, today i will give some little insight into a wonderful sea creature that we may have not had time to know about "the octopus". As many that like this post endeavour to upvote me.
THE OCTOPUS_ 001
The octopus is a soft-bodied, eight armed mollusc of the order Octopoda . Octopuses are ocean creatures that are most famous for having eight arms and bulbous heads. They have three hearts and blue blood, the blue color comes from hemocyanin, the copper containing protein that binds oxygen in the octopus.In addition to being blue, octopus blood is a poor carrier of oxygen, which helps explain the animal's sometimes apparent laziness. To cope with the low oxygen levels, the octopus maintains a constant high blood pressure and has three hearts. Two of the hearts pump oxygen rich blood through the gills, while the third circulates it through the rest of the body.
They squirt ink to deter predators; and being boneless, they can squeeze into (or out of) tight spaces. They are quite intelligent but sadly for them sex is a death sentence. Around 300 species are recognize and the order is grouped within the class Cephalopoda with squids , cuttlefish and nautiloids . Like other cephalopods, the octopus is bilaterally symmetric with two eyes and a beak , with its mouth at the centre point of the arms, which are often mistakenly called "tentacles". Most octopus species have suction cups on the bottom of each arm. The arms seem to have a mind of their own. In fact, two thirds of an octopus' neurons are in its arms rather than its head. That means that an octopus can focus on exploring a cave for food with one arm while another arm tries to crack open a shellfish.
