Doesn´t look like much but have you ever asked yourself what this animal was like when it was alive? I´m going to prove to you how cool octopuses really are:

It is well known that octopuses have four pairs of arms although they have neither an internal, nor an external skeleton. This means that they have no bones or a shell, which is the reason why they can squeeze themselves through very tight and small places. Still their tentacles break when they are damaged. Another extraordinary thing about them is that they have blue blood and three hearts: two for pumping the blood through each of their two gills, one for pumping blood through the rest of their body. But the structure of their body isn´t the only impressive thing the octopus is offering.

Octopuses are unexpectedly intelligent animals. They can store both, short- and long-term memories. Also you can teach an octopus behaviour but they usually don´t learn from their parents because they wouldn´t live long enough. And although octopuses are colour-blind they can adjust to their surrounding perfectly in a few seconds, just like chameleons. This can be used as a defence mechanism or a tactic to attack their prey. Continue reading Octopus
