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



After preparing a Nudibranch emoji and sending it and the form to Unicode for approval there came an email later rejecting the Nudibranch emoji - "The potential usage and statistics do not meet current expectations, although the proposal is nicely done." So you see there will never be a Nudibranch emoji...

Pic of the Week


First and last seen in the Maroochy River.


Plocamopherus sp. 2

The Mooloolah River yet again gives up another beauty


Plocamopherus sp. 2 was first found in the Maroochy River a few years ago and has now been recorded in the Mooloolah River.


This 40 mm beauty is one striking animal. To escape danger it lifts off the substrate and thrashes side to side. Its paddle shaped tail and wide head give the animal flight. It also can lay it's rhinophores down flat when thrashing. This undescribed species is characterised by a white body with brown spots and blotches with orange margin, rhinophoral cups and gill bases. This animal has dorsal protuberances on each side of the body.

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 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.


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!

About this Nudibranch website

NOTE: From 2003 to 2018, content on this website was generated by Gary Cobb, David Mullins, with Terry Farr and Julie Schubert. From 2019, content has been generated by Gary Cobb.


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.
