When will it stop!

Well after almost 7 years of extensive searching by the team of Nudibranch.com.au we have found total of 409 species. That is an average of 1 new one every weekend! We have found Nudibranchs in every possible surrounding. The sizes vary from 0.8 mm up to 400 mm. Some are very brightly coloured, yet some are so cryptic it is wonder if anyone would have found them other than the team. It is very exciting when we find a NEW species. SO, the question arises...will it end?
The Ocean hold many secrets and it would not surprise me if it never ends. With global warming, ocean currents and other factors new species are showing up in our "back yard". Freinds often ask why we don't go overseas and search there...that is an easy question to answer. We have a very diverse "backyard" and we believe finding new Nudibranchs will go on until we can't search any longer. Of course that will not happen!! HeHaa!
Keep searching!

Why the Lists and How we do it

First thing we do after ascending is set our cameras and put our glasses over our mask. We travel very slowly and search every inch of substrate. When we find a nudibranch species we take a photo of it, that way it is recorded. If we find one that is NEW we photograph it and collect it to look at more closely and study it's behaviors, plus see if it lays eggs. If this animal is new to science we preserve it for the Museum.

The List is a recording of nudibranchs we see on every outing. It shows what the common species are and how often we find the not so common ones. Plus it is an incentive to break the record.

Cheers...see you at the bottom!
