The octopus has always been the stuff of spine-tingling legend, like that of the Kraken, the many-armed sea monster believed to drag ships to the bottom of the sea after dining on the crew. Or Gertie the Pus, the giant Pacific octopus that lives under the Narrows Bridge connecting Tacoma, Washington to Gig Harbor.
In reality, the octopus is more benign but equally fascinating. Did you know the octopus has two-thirds of its brain neurons distributed throughout its eight arms? Or, that the severed arm of an octopus can walk independently toward a food source and move it to where its mouth should be?
