Nudibranchs of the Sunshine Coast,
Queensland, Australia, Indo-Pacific

Pic of the Week


Looks different and is different.


Goniobranchus sp. 10

A closer look reveils a new species!


During a recent dive in the river I recorded what I thought was Goniobranchus daphne. After I shot two photos I thought this looks different and then continued my search. When I got home and reviewed the photos and I discovered that the margin has no red accept on the anterior end. There is some yellow tinting on the dorsum and the red spot also look different.


This new species is recognised by it's white margin with a yellow submargin. The body is white with red spots. The rhinophores and gills are red.


The river continues to deliver new and exciting Nudibranchs.

Our Mission

LOCATE, RECORD, IDENTIFY and POST every species of HETEROBRANCH to be found on the Sunshine Coast Queensland, Australia.


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 from qualified 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.


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!


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.

About this 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.
