Nudibranchs of the Sunshine Coast,

Diacavolinia longirostris

After a dive in the Gneering Shoals recently, while hanging at 5 m for a safety stop, an unusual "flying" critter was swimming toward my face. I instantly knew this was a Pteropod and quickly collected it to ID later.

 

For over 17 years I have been trying to record one of these but no luck until that dive. Finally a live Diacavolinia longirostris was found.

 

At 7 mm this "Sea Butterfly" is a pleasent surprise. The specimen will reside at the Western Australian Museum.

 

This species was described from its shell. No mention of what the animal looks like. The animal has two large wings that are constantly flapping. The animal lives in a shell that is likened to a clam with a triangular shape. It swims its whole life in the plankton rich oceans which it eats.

 

In 2016 I managed to record a shell from this species on the deck of the HMAS Brisbane wreck, that was the first time there was evidence of Pteropods here on the Sunshine Coast.

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
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.
