Scientists have been looking to nature for inspiration for materials with useful properties. Insect exoskeletons and shark skin are examples of materials that exhibit strength, durability, and less ...

Northern Map Turtles, Graptemys geographica, are a long-lived riverine species of conservation concern. We examined carapace morphology of Northern Map Turtles at Mount Union, a major turtle nesting ...

In a university swimming pool, scientists and their underwater cameras watch carefully as a coiled shell is released from a pair of metal tongs. The shell begins to move under its own power, giving ...

IT is known that the form of the shell of Portuguese oysters (O. angulata) living on the shore is different from that of individuals living permanently below tide-marks 1. In the latter the shell is ...

Long before the first dinosaurs roamed the earth, the oceans were full of creatures known as ammonites. Scientists have now created a number of robotic ammonites, to see how the different shell shapes ...

Robotic ammonites, evaluated in a university pool, allow researchers to explore questions about how shell shapes affected swimming ability. They found trade-offs between stability in the water and ...
