Images and Information About Nudibranchs & Sea Slugs
from Around the World
Nudibranch Domain is a resource for enthusiasts, divers, photographers and researchers who want to discover more about nudibranchs and sea slugs of the marine heterobranch group on the Sunshine Coast, Australia, the Indo-Pacific region and around the world. Although many nudibranchs are visually striking, this site goes beyond beautiful underwater photography to provide species information, identification guidance, biological details and useful references.
Nudibranch Domain features an image of every nudibranch and sea slug species recorded on the Sunshine Coast in southern Queensland, Australia, by the Sunshine Coast Sea Slug Survey Team.
As the site grows with new dive reports, additional photographs, species descriptions, identification details and scientific references are added to each profile, creating an increasingly valuable resource for anyone interested in nudibranchs and marine biodiversity. So bookmark the site and return often to learn more.
The Survey Team has also recorded many hundreds of Indo-Pacific sea slug species during overseas expeditions. These species are added regularly, greatly expanding the site’s coverage of nudibranchs from around the world.
