How the Squid Lost Its Shell

2018• 9 minG

Synopsis

Ancestors of modern cephalopods like octopuses and squids possessed shells that initially provided protection but ultimately became a liability in their evolution.

Synopsis

Ancient cephalopods, the ancestors of modern squids and octopuses, possessed shells that provided protection and buoyancy. Over time, these shells became a liability, leading to the evolution of the soft-bodied cephalopods seen today. "How the Squid Lost Its Shell" explores this significant evolutionary transition, highlighting the advantages and disadvantages of shell loss. The documentary features the paleoart of Nobumichi Tamura and cephalopod reconstructions by Franz Anthony, showcasing the fascinating history of these marine creatures.
