Nudibranch Domain
Images and Information about Sea Slugs from around the world
This is a site for aficionados of nudibranchs and their sea slug relatives, who want more than pretty pictures. At the launch the site is populated with an image of each species sighted on the Sunshine Coast, southern Queensland, Australia by The Sunshine Coast Sea Slug Survey Team.
As the site develops, information, more images and references about each of the species will be added providing a helpful and valuable resource. The many hundreds of Indo-Pacific species, recorded by The Team when overseas, will also be regularly added significantly broadening the resource.
There are three ways to get your hit of Sea Slug knowledge.
- Species Profile features information about specific sea slugs. Navigate, Identify and Learn about species via the lists. Notification of the latest expanded entry will appear below on the Home Page.
- NudiNote features specific topics that can be sourced via its Archive. Notification of the latest entry will appear below on the Home Page.
- Understanding Nudibranchs is a book on general sea slug biology and behaviour that will be posted in parts, as they are completed.

The Sea Slug Snippet

Chromodoris joshi Gosliner & Behrens, 1998
The specimen shown here is a colour morph of this species. It has the identical genetic make-up as the much different looking, originally described, typical type (see its Species Profile for comparison). The colour morph is white with three black longitudinal bands having blue colouration in-between but white outside. There is a thin white marginal line to the mantle with a broad yellow submarginal band. Rhinophores and gills are orange.
