How Octopuses Camouflage And Much More

In the depths of the ocean many animals have evolved to use camouflage as a self defense technique. But how? Because that would be very useful to me. Unfortunately only selected animals can camouflage because you need these cells called chromatophores which are pigment containing and light reflecting organelles. The Octopus (and many other animals that can camouflage) can control these cells with their brain. Imagine changing your skin color by just thinking about it. In addition to changing it's skin color the octopus can shrink and stretch it's skin to make it look like a different texture.

If this animal wasn't cool enough, octopuses also have 3 hearts. 2 pump blood through each of the gills and 1 pumps blood throughout the body. Another self defense technique is that octopuses release black cloud when spotted, this gives the octopus time to swim away. The black ink has a substance to dull the predators sense of smell making it harder to attack the octopus. And if all else fails a octopus can lose an arm to escape the predator's grasp and grow it back later.  How cool.

The most famous octopus of them all.
