I've seen a TV program about camouflaging animals. The TV program introduced a camouflaging animal in the sea -- the name of that animal is "Blue-Ringed Octopus".

This octopus is good at hiding because he has abilities to camouflage. He can change his skin colour as he pleases.

Look at the right picture. The animal you can see is the Blue-Ringed Octopus but his skin colour is different from his normal state (like the above picture). 
He uses camouflage to hide and looks the same as the background.


Not only Blue-Ringed Octopus but also most octopuses and cuttlefish can change their skin colour quickly. They have a lot of pigment cells under their skin, so they can make various colour patterns on their body. 


Blue-Ringed Octopus is very small, beautiful octopus. However, we must understand that this octopus is one of THE GREAT DANGER animals. Blue-Ringed Octopus is a VENOMOUS octopus. If we are bitten by them, we are died.

That is why we must not touch rashly this octopus.
