Cuttlefish camouflage under extreme flooding events

Extreme events are becoming increasingly frequent and intense, leading to cascading negative effects on marine ecosystems. Here, we aimed to investigate the impact of ecologically relevant extreme flooding conditions (exposure to acute salinity values of 17 and 7) and non-extreme conditions (salinity values of 35, 28, and 24), during 4 days at late embryogenesis, on the survival and camouflage abilities of the European cuttlefish (Sepia officinalis) hatchlings.
