Two Colours - One Species.

 

Pleurobranchus peronii

There are a number of species of sea slug that present in different colour forms. Pleurobranchus peronii is one such sea slug presenting mostly as either an orange or port wine colour but even many shades in between have been recorded. The tubercles that cover the mantle are polygon shaped and are sometimes outlined in a darker or lighter colour. Some specimens have a darker spot in the centre of the tubercles.

 

Last week the orange specimen here was photographed at Flinders Reef whilst the reddish specimen was photographed at Currimundi Reef; both sites in SE Queensland. Both colour forms of this species shown above have even been sighted by the author under the one rock.

 

Confusion between colours and even the different appearance of the juvenile has lead to at least 7 other names (considered synonyms) being ascribed to this species.

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.

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.

 

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

Parting note.

Nudibranchs are 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. Learn more>
