Presenting a new species of Nudibranch recorded at La Balsa Park...


Naisdoris labalsaensis is a species that was recorded in the Mooloolah River at La Balsa Park. This beautiful species was once thought to be Okenia liklik but after DNA work was done there is a new species named in honour of the location from which it was recorded at.


This small species, only 5 mm, has a brilliant pink coloured body mixed with white. The margin is saw-toothed. Oral tentacles are yellow and tipped in black.


The total number of newly described species from La Balsa Park is 12...Amazing!

My Mission

LOCATE, RECORD and IDENTIFY 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 of the specimens.


To IDENTIFY these species through invaluable support from qualified authorities in this field and developing reference resources.

About this Nudibranch website

I embarked upon this adventure while diving here on the Sunshine Coast, Queensland, Australia 21 years ago. Upon realizing the amazing variety of nudibranchs I was seeing, I 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 mine suggested I share the knowledge with the world. The site commenced in March 2003 when I 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.
