Nudibranchs of the Sunshine Coast, Queensland

Nudibranchs attract Wren


Exploring Alex Headland

Wren, aged seven, first saw a nudibranch on April 6th 2017 on the beach at New Brighton in northern NSW, just up from Brunswick Heads, we were walking back from North Head national park, and it was a wild afternoon, with turbulent skies and a big ocean to match.


She spotted the first one, in amongst the blue bottles, and then hundreds and hundreds of them. Perfect shiny blue and silver jewels washed up on the beach. And after marveling on her hands and knees at the first few, for nearly an hour, she diligently picked up each one and returned them to the waves.


We now know these were Glaucaus atlanticus, armed with the internet we discovered Nudibranchs. We read, and Googled, and discussed and she never forgot these elegant brilliant little creatures – always looking for them when we were at the beach (which is very often for us).


Eight months later, at the same coast we found ourselves walking the dogs up near South Golden beach and shrieks of delight - it seems we had found a plethora of the same variety again – but on researching we now understand them to be Glaucus bennettae, much tinier and more fingery than their larger cousin and yes, she returned these to the ocean too.


The questions came in "mum, why do I have to be 12 before I can learn to scuba dive?" "mum, what is a nudibranch expert called?" "mum, I want to be a nudibranch scientist" "mum, which university does nudibranch science" it seems the Mum has to do some research herself.


She starts secretly commandeering my Iphone and covertly watching documentaries on Youtube on nudibranchs.


Once more to the internet we go, and I find a web site – a local web site (if there is such a thing) and aside from unlocking many nudibranch mysteries to us it tells me that we are blessed to have a world recognized expert in nudibranch identification living only 90 minutes away.


And so I email, I email asking what books I can buy, how I can help support my daughter's interest in this bizarre animal. It's Christmas holidays, it might have even been Sunday, and 20 minutes after I send the email I get a phone call. Many suggestions made, Nudibranch Encyclopedias, Intertidal Zones to go rummaging.. plan made, with a promise to stay in touch.

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

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.
