If you're one of those people who, when referring to octopuses, exuberantly exclaim "They have eight arms!", science has made you look foolish. And will now proceed to mock you mercilessly.
Scientists in Germany have revealed that two of an octopus' appendages are used as legs, while the remaining six are used as arms. The study also indicates that octopuses are neither right or left handed, forever stymying Major League pitching coaches with a thing for tentacled closers.
It's also interesting that octopuses are among the world's most intelligent invertebrates, even able to use small tools. Why, there's even an octopus in Cornwall that loves its Mr. Potato Head. Truly, one of nature's more confounding and appendaged creatures.
