Editorial Analysis
The ancestors of modern, squishy cephalopods like the octopus and the squid all had shells. In ancient times, their shell was their greatest asset but it eventually proved to be their biggest weakness.\n\nSpecial thanks to Franz Anthony for the beautiful cephalopod reconstructions.
