How the Octopus Moves
It must be convenient having eight limbs—but also, that's a lot to keep track of. How do octopuses* manipulate their limbs to move? And how is it that they can move so well, even when their eyes are looking in another direction? Is the octopus's brain dealing with the precise location and movement of tentacles it can't even see most of the time?
In this short explainer from The New York Times, we see the results of a research study that examined octopus movement and came up with an interesting conclusion. This will just take a minute:
* = The plural of "octopus" is properly "octopuses" or "octopodes." Wikipedia has a good explanation of this. "Octopi" is not the preferred nomenclature, dude.
