Octopuses are the greatest animals living on planet Earth. Fact.
We've got a whole gallery of reasons to convince you as to why this is so - but it starts with a new piece of research from researchers at the University of California, Berkeley and Harvard University.
In short - the humble octopus sees colours in a totally unique, insanely cool way.
They change the shape of their eyes to view different colours
Which helps explain how they figure out how to change colour
They have the most insane camouflage skills you've ever seen. Or, rather, not seen.
They're super intelligent
Okay, not like Hawkins-intelligent - but the average octopus is more intelligent than your beloved dog.
Observe this little guy use coconuts as a shield/tool/safety mechanism. Just brilliant.
They can fit through anything their beak can squeeze through
The only 'hard' part of an octopus is it's "beak" mouth. That means that if the beak fits, the rest of its body can be squeezed through any manner of crack or crevice.
Which is terrifying.
They can solve problems
Look at it, solving that problem.
No one is safe
Think they only hunt stuff in the ocean? Think again, as you watch in horror at the spectacle of an unwitting seagull being grabbed from beneath the waves, dragged into a grim embrace.
