Over the centuries, the empire’s grass bridges gradually gave way, and were replaced with more conventional works of modern engineering. The most famous Incan bridge—the 148-footer immortalized by Thornton Wilder in The Bridge of San Luis Rey—lasted until the 19th century, but it too eventually collapsed. Today, there is just one Incan grass bridge left, the keshwa chaca, a sagging 90-foot span that stretches between two sides of a steep gorge, near Huinchiri, Peru. According to locals, it has been there for at least 500 years.

Canine Teeth.
Photography by © (Kieron Nelson). The long canine teeth are also important, in that they hold and subdue the prey. Capable of delivering up to 10,000 kPa (1450 lbf/in²) of pressure, a wolf’s teeth are its main weapons as well as its primary tools. This is roughly twice the pressure that a domestic dog of similar size can deliver. The dentition of grey wolves is better suited to bone crushing than those of other modern canids, though it is not as specialised as that found in hyenas. #wildlife #grey #canine_teeth #yawn #ontario_canada #wolf #timber_wolf #open_mouth
