Pedalternorotandomovens Centroculatus Articulosus


"The Pedalternorotandomovens centroculatus articulosus came into being (generatio spontanea!) as a result of dissatisfaction concerning nature’s lack of any wheelshaped living creatures endowed with the power of propulsion by means of rolling themselves up. So the little animal shown here, known in popular parlance as the ‘curl-up’ or ‘sausage roll’, is an attempt to fill a long-felt want.

Biological details are still scarce; is it a mammal, a reptile or an insect? It has a protracted body made up of horny articulated sections, and three pairs of legs the extremities of which resemble the human foot. Placed centrally in the thick, round head (shaped like an acutely curved parrot’s beak), are the bulging eyes, on the ends of stalks and sticking far out on either side.

In its fully stretched position this creature can move slowly and gingerly forward, by using its six legs, over almost any type of terrain (it can, if occasion arises, climb up or down steeps, stairways, penetrate undergrowth or clamber over chunks of rock). But as soon as it needs to undertake a long journey and has the advantage of a suitable level path for the purpose, it presses its head on the ground and rolls itself up with lightning speed, pushing itself with its legs, in so far as they touch the ground. In its rolled-up position, it has the shape of a discus, the central axis formed by the eyes on stalks. By pushing out each of its pairs of legs in turn it can get up a high speed. Furthermore, it is thought ot be capable of retracting its legs and freewheeling onwards (for instance when coming down a slope or going full tilt).

Whenever it has reason to do so, it is able to return to its walking position by one of two methods:

(i) an abrupt stop brought about by suddenly stretching its body, in which case it ends up on its back with its legs in the air;

(ii) a gradual reduction of speed, using the legs as brakes and coming to a halt by slowly unrolling backwards."
[By M.C. Escher, November 1951 litograph]

Little did Escher know that nature had already created his Pedalternorotandomovens Centroculatus Articulosus. Without "generatiospontanea", as a result of the always surprising natural evolution. And not only once, but many times over, in several different variations.

Pill bugs and other armored things

Bear with me, it’s not my intention to present pill bugs (Armadillidium) as amazing wonders of nature. Even if they really are, capable of transforming into near perfect little balls able to roll around. Several other very well-known creatures such as the Armadillo, or the Hedgehog and many other animals like the less well-known Pangolin are all capable of curling up like spheres to protect themselves. To protect themselves.

[ It’s no Firefox, it’s a
Pangolin, which would also make a cool browser name ]

And here lies Escher’s genius. I guess he probably knew Armadillos and Hedgehogs, probably even Pangolins and certainly pill bugs. But those are all creatures who become sphere-shaped for protection, while Escher’s imaginary ‘thing’ becomes a wheel with the specific aim of locomotion. The wheel shape is adopted as it reduces drag over level areas allowing high speeds with little effort. As a bonus, his imaginary creatures are also able to self-propel themselves while still being a wheel.

Do you know any creature that does these things?

Escher didn’t, and “to fill a long-felt want” he invented it. But as we already revealed, nature had already come to these ways, even if science would still take some years after 1951 to discover them. So, finally…

Carparachne aureoflava

Golden wheel spiders (Carparachne aureoflava) of the Namibian desert have a somewhat harsh life. They don’t produce webs, and their defense consists in burying themselves under almost half-meter of sand. For a spider less than an inch in size, it’s quite hard work. And if their lives are difficult, their deaths may be horrible, as preying wasps are also very good sand diggers who can penetrate the spider sand fortress with a terrifying aim: to paralyze the arachnid and inject eggs inside them. The spider, still alive but paralyzed, is then buried by the wasp to become food for the growing offspring inside it. Eaten alive, from inside.

To escape from this most inconvenient end, the golden-wheel spider has one more defense mechanism. If its sand fortress is uphill, when it’s exposed by the wasp it can simply curl its legs and become a wheel, able to roll down the sand dunes. It can spin several dozen times a second, reaching a speed of up to 1m/s. For a spider less than an inch in size, it’s quite a formidable speed.

And it’s much like the imaginary animal capable of moving carefully with its legs or, when necessary, becoming wheel-shaped and rolling around to travel with speed and little effort. There’s another good video of this fascinating creature in "Buggin’ with Ruud: Golden Wheel Spider".

If the golden wheel spider fulfills Escher’s basic idea, amazingly, there’s another real creature that’s does it almost exactly the way he imagined.

Nannosquilla decemspinosa


The behavior of this little sea crustacean, Nannosquilla decemspinosa, was first described by Roy Caldwell in 1979, almost 30 years after the Pedalternorotandomovens.

It’s a creature so small and thin that it can’t walk in dry land, which is a problem when the ocean throws them in the beaches. A problem solved with some of Escher’s genius, developed through millions of years of evolution. As can be seen in the above illustration (from left to right), the little N. decemspinosa can curl-up around itself, and by doing this repeatedly, performing several dozen ‘somersaults’ as Caldwell called it – notice that it’s curling backwards – it’s the only known animal capable of wheeling itself even uphill.

Sadly, I couldn’t find any video of this fantastic little thing. But from it’s general appearance to its “wheeling” behavior, it’s almost exactly Escher’s creature living around. Escher would make a good watchmaker, as there can’t be a better proof than reinventing the wheel-shaped animals that nature’s blind watchmaker took millions of years to develop.

Keep reading for some bonus nature-wheeling.

Skeptical UFO Newsletter… lite!

Good news, everyone! Fellow Tim Printy writes:

SUNlite, as I call it, is dedicated to the skeptical information and opinions regarding Unidentified Flying Objects (UFOs). In 2003, Phil Klass ended his publication of SUN due to his failing health.  In an effort to fill the void left behind, I have decided to endeavor in producing this newsletter.   I want to encourage submissions for the newsletter from fellow skeptics and UFO proponents alike. All articles should be skeptical of claims that UFOs are alien spaceships because that is what this newsletter is about. I have no desire to present conspiracy theories I do not agree with or to make great leaps that, because a UFO can not be explained, it is an alien spaceship.  The first day of the month of issue is when to check the site for the latest issue. It should be there but if it isn’t check back in a few days. I may be too busy or sidetracked. Any articles or comments should be directed to my email address: [email protected].  Many thanks to those providing input and assistance for the newsletter.”
