New Record for the River.
Okenia pellucida
The Mooloolah River at La Balsa Park is always presenting new and unexpected species of Nudibranch quite regularly. Here is one of those pleasent surprizes...
Okenia pellucida has been found at the Newport Marina, Scarborough, Redcliffe Peninsula, Queensland. This species has only been seen in our survey area one time. To see it thriving in the River is a joy.
This species was described by Bob Burn in 1967.
The white elongated body has an irregular network pattern of thin dark brown lines. There are the characteristic papillae along the sides of the dorsum. Two animals were sighted. It is always associated with the ctenostome bryozoan Zoobotryon verticillatum on which it feeds and lays its egg masses. 15 mm

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 20 years ago. 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.
NOTE: This website is not "definitive", as some do claim, we don't claim to be, but, it does show the viewer pretty pictures of what we find here in our wonderfully diverse backyard...Enjoy!
nudibranch.com.au 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.
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.
