Prowling Octopus Camouflages Quickly
Cloaked in color-changing chromatophores, an octopus slinks along the seafloor--until it pounces on its prey. Our team spotted this octopus predation event recently in Channel Islands National Marine Sanctuary while exploring ancient submerged shorelines.
The Channel Islands National Marine Sanctuary (CINMS) is one of the agencies tasked with the protection of deep-water habitats, commercially important species, and deep sea coral ecosystems around the islands, yet lacks a detailed understanding of the distribution, abundance, and condition of the resources within the Sanctuary. Less than 50% of the seafloor within the CINMS boundaries has been mapped by high-resolution sonar, and the 2016 Nautilus expedition to the same region worked to cut this knowledge gap nearly in half.
