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 ...

Scientists have now created a number of robotic ammonites, to see how the different shell shapes they evolved affected their movement through the water. Ammonites belonged to the cephalopod group of ...

In Baculites, a straight shelled ammonite, the constructional limits on shell shape resulting from the limited strength of nacre in tension are circumvented by a system of vaults in the phragmocone.

Scientists scanned a fossil of the Jurassic cephalopod Vampyronassa, pictured here, and found clues that it was an active hunter. A. Lethiers, CR2P-SU Finding and studying fossils of Earth’s ...

SEATTLE, November 25, 2019 - Computational fluid dynamics can be used to study how extinct animals used to swim. Scientists studied 65 million-year-old cephalopod fossils to gain deeper understanding ...

Camouflage isn't the only way cephalopods have evolved to change their appearance. Octopuses and other cephalopods make the fastest transformations in the animal kingdom. Here, a giant Pacific octopus ...

This is a guest post by Dr. Danna Staaf, a science writer with a PhD in marine biology from Stanford University. Her first book, Squid Empire: The Rise and Fall of the Cephalopods, chronicles the ...

The oldest ancestor of modern octopuses lived 328 million years ago and had 10 arms, according to a new study. Researchers have named the previously unknown species Syllipsimopodi bideni after US ...

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 ...
