Beachcombers know that seashells appear in an endless array of colors and shapes, and researchers have just discovered that this variation extends to the molecular level. In fact, each shell is as ...

Scientists devised a mathematic model that helps explains how Nipponites, some of the wonkiest ammonites, built their shells. By Sabrina Imbler If you’ve seen one ammonite, you may think you’ve seen ...

Researchers modeling the tough exteriors of two types of mollusk have finally figured out how seashells keep those soft, squishy insides safe. Thanks to the shape, stress is sent to the parts of the ...

Everybody knows how oysters make pearls-- a bit of sand or grit slips through the protective barrier of their outer shell, irritating the mollusk's body, and the invertebrate encircles the invader ...

Engineers analyzed seashells to see how their shapes contribute to their remarkable strength. By modeling the average mollusk's mobile habitat, they are learning how shells stand up to extraordinary ...
