Octopus Phylum mollusca 9 Class cephalopoda 9 Order-octopoda 9 Octopuses are called “head footed because their tentacles are coming straight from the head, no body 9 Interesting fact is that they have blue blood because of hemocyanin. The blood is pumped by 3 hearts, 2 for oxygen-rich blood to the gills and 1 for the rest of the body 9 Masters of camouflage-They have sacks with pigments called chromatophores. They are surrounded by muscles which allow the octopus to control its color. 9 Like their close, relatives the squids, octopuses release ink when they are in danger 9 Octopuses may look lazy, but when they find themselves in danger they can boost up to 40 kph. They pump in water and release it with their funnel with great speed 9
