Nudibranchs of the Sunshine Coast, Queensland
Gary, David, Julie and Terry

Pic of the Week


A Most Elegant Poop


Tritoniopsis elegans

The Nudibranch Team has been busy this last week doing what they do: recording the sea slug life in their backyard - the Sunshine Coast waters of south east Queensland, Australia.
Dr. Bill Rudman of Sea Slug Forum fame always welcomed any records of nudibranchs, but he was especially happy to receive images of nudibranchs in which they are, to use his words: "doing things".


Last Wednesday on Currimundi Reef we thought we had hit the jackpot with not only a rarely seen here, orange tinted Tritoniopsis elegans, but it was finishing off laying its spawn spiral. Notice that the eggs are grouped into packets and it is these packets that form the spiral. But hold on - something else is going on, or should we say coming out. Yes, a scatological moment recorded for prosperity.


Unlike the cryptobranch dorids, where the anus is located on the dorsum, posteriorly, in the centre of the gill circle, in the dendronotids it is on the right side of the body wall approximately halfway along its length, and in the above image we can see a faecal pellet being discharged at that point. The genital orifice from which the eggs are laid is also located on the right side but only about a quarter of the way back and lower on the body wall.


I guess we could say it is multitasking.

Our Mission


Branchers PsalmLOCATE, RECORD, IDENTIFY and POST every species of OPISTHOBRANCH to be found on the Sunshine Coast Queensland, Australia. Learn more>


To LOCATE through scuba diving and intertidal searching.


To RECORD by underwater and studio/taxonomic photography (including microscopy photography) of the specimens.


To IDENTIFY these species through invaluable support fromqualified authorities in this field and developing reference resources.


To POST upon our web site not only images of the species and their natural history behaviour but also information concerning size abundance and localities. Additionally to disseminate to other sites information considered unusual (see Useful Resources).


Towards achieving these aims we will continue to acquire and develop the necessary equipment, resources and knowledge.


Have fun, learn and enjoy the Earth's greatest creatures!

Gary, David and the Team

Parting note.

Nudibranchs are amoung the most ephemeral of marine creatures. They greatly vary in size, colour and shape. They can be almost invisible or very bright and easy to see. Learn more>

Our Nudibranch website


We embarked upon this adventure of ours while diving here on the Sunshine Coast, Queensland, Australia. Upon realizing the amazing variety of nudibranchs we were seeing, we developed an appetite for not only finding as many different species as possible but identifying and learning all we could about these most amazing creatures of the sea.
Naming Nudibranchs was born when a friend of Gary’s suggested we share our knowledge with the world. The site commenced in March 2003 when we set out on our quest to find, identify and record all of the nudibranchs here in our area. The ever changing sea and seasons give up new surprises every visit whether they are subtidal or intertidal.

We describe our searching and identifying component of the quest as The Treasure Hunt, and the recording thereof upon the web site as The Never Ending Story.


We welcome for inclusion on the site the findings of other workers in this area that we may not have yet recorded.


From this website a Nudibranch Identification book called Undersea Jewels - A Colour Guide to Nudibranchs was published in 2006. The book is a 'Colour Guide'. After all that is the first thing anyone remembers about first seeing a Nudibranch.

We note the publication of recent scientific research regarding the Flabellinidae family by Korshunova et al, (2017). As this research potentially affects a large number of species, we have elected not to update the website with name changes at this point in time, pending comments on the publication from the wider scientific community.

Korshunova T, Martynov A, Bakken T, Evertsen J, Fletcher K, Mudianta WI, Saito H, Lundin K, Schrödl M, Picton B (2017) Polyphyly of the traditional family Flabellinidae affects a major group of Nudibranchia: aeolidacean taxonomic reassessment with descriptions of several new families, genera, and species (Mollusca, Gastropoda).
