Or they are, at least, in the hands of nature cartoonist Rosemary Mosco, creator of Bird and Moon Comics.
To the animals that wield them, however, warning coloration, aggressive poses, and intimidating anatomical features can mean the difference between death and a last-minute escape – even (or, perhaps, especially) when those animal are bluffing.
Note that though the snake is shaking it’s tail like a rattlesnake, it is not illustrated with a rattle, so many readers of the original article, as well as myself, have concluded it is most likely a non-venomous snake that imitates rattlesnakes as a defense mechanism.
What kind of other creatures do you know of that have amusing defense mechanisms and/or threat displays?
A 3D printed robotic prosthetic hand which is a fraction of the cost compared to current available models - video embedded below:
The Open Hand Project aims to make advanced prosthetic hands more accessible to amputees. The Dextrus hand is the realization of this goal, it’s a low-cost robotic hand that offers much of the functionality of a human hand. Ultimately, these hands will be sold for under $1000 (£630).
The Open Hand Project is open-source, which means all of the plans to make a robotic hand will be published online with no patents, anyone has the right to make their own and even sell it themselves. You’re funding the full development of the hand with the Open Hand Project, after that companies will be able to use the designs and sell the hands all over the world. This really helps get these devices out to developing countries and places where import taxes might otherwise increase the cost of distribution.
The project is looking for funding through an indiegogo campaign - more info can be found here
There is no such thing as coincidence. If it was fate that brought you here, it was surely some other higher power. Now that you're here, leave your mark. http://glennfriesen.com http://shellandbone.com
