Where did squid come from?

Squid are believed to have evolved from ancient cephalopods that lived in the oceans over 500 million years ago. Their evolutionary lineage can be traced back to a common ancestor shared with octopuses and cuttlefish. Fossil evidence suggests that modern squids emerged during the Late Cretaceous period, adapting to a variety of marine environments over time. Today, they are found in oceans worldwide, showcasing a diverse range of species and adaptations.
