Opalescent Inshore Squid

Imagine a shimmering cloud of iridescent jewels darting through the water – that's likely your first encounter with the Opalescent Inshore Squid (Doryteuthis opalescens). These small cephalopods, typically around 13cm but occasionally reaching 19cm, are a true spectacle. While not typically found in shallow waters frequented by snorkellers, scuba divers exploring depths of 20-180 meters in the Northeast and Eastern Pacific have the best chance of witnessing their mesmerizing displays. These squid often gather in large aggregations, particularly during spawning season, creating a breathtaking underwater ballet of flashing colors and coordinated movements. Their ability to rapidly change color and their intriguing social behaviors make them a highlight for any dive.
