What this basically means is that this soft bodied creature, equipped with three hearts and blood that uses copper instead of iron to transport oxygen, is more closely related to snails and clams than it is to you or any other vertebrate.
This simple fact is what makes this small octopod's behavior so amazing.
You see, this remarkable creature uses tools.
So what does this remarkable little guy do? He gathers up discarded coconut shells and other similar debris, sometimes carrying individual pieces as far as 65 feet.
Then he carefully arranges them into a well built shelter where he can hide with confidence.
Just think, it was only a few decades ago that scientists discovered that chimpanzees use tools, and now we're finding that even invertebrates are capable of such feats.
These truly are exciting times, and as humans probe deeper into the minds of our fellow species I can only hope we develop a greater respect and appreciation for the life that surrounds us.
