The authors, Eliza Heery and colleagues at the Seattle Aquarium, NOAA, and the University of Washington, used REEF sightings data on Giant Pacific Octopus (Enteroctopus dofleini) in Washington State to evaluate patterns of occurrence with urbanization. The species is the largest known octopus in the world, and they can reach over 20 feet in length from one tentacle tip to the other. The study objectives were to determine whether the distribution and habitat-use patterns of Giant Pacific Octopus were correlated with urbanization intensity on nearby shorelines in Puget Sound.
A quick introduction to the project and how to conduct your first survey underwater. Snorkelers and divers both can participate in this volunteer citizen science project.
