NOTE: Unfortunately, we can’t embed the full video, so see the footage in its entirety here, or watch a shorter clip above.

We never knew until recently how intelligent and terrifying octopuses really are — the answer is a lot. This video only further cements the idea.

We might call this octopus clever if it didn’t seem so sinister. Just look at those little slotted eyes poking from behind the shell. These creatures are plotting world domination, one rock crab at a time.

This video shows several fascinating sea creatures in action beyond the veined octopus, and serves as a testament for the colorful, weird worlds that lie beneath the ocean surface. Appreciate nature, even as it revolts you, with the awesome video above.
