Nudibranchs of the Sunshine Coast, Queensland

Congress on Codium

 

Elysia maoria

Looking down on the substrate of the offshore reefs of southern Queensland, you will sometimes notice little patches of green. What you see may be a green alga of the genus Codium. Codium, depending upon the species, comes in two main shapes - erect with finger-like branching and prostrate with globular lobes. They have a velvet appearance to their surface.

 

If you take the time to slow down and examine these little green patches or undulating lobes you may sometimes be rewarded by finding tiny little sacogossan sea slugs - Elysia maoria - living thereon feeding, mating and laying spiral egg coils, effectively there for their entire adult lives. Curious to relate, these little hermaphrodite sea slugs mate through hypodermic insemination. The body wall of a partner is pierced and sperm is deposited directly into the body cavity eventually making its way to fertilise the eggs.

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
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.
