I began diving in 1975 and immediately became addicted. Underwater photography soon became an important part of my diving and I now have a large collection of marine life images. I enjoy studying the scientific aspects of the fish and invertebrates in my photo collection. I go on 3-4 liveaboard dive trips a year to various locations in the the tropical Indo-Pacific. In 1999 I retired from my anesthesiology practice and now have more time for diving and photographing nudibranchs and other beautiful marine creatures

In 2001 I received the appointment of Museum Associate in Malacology at the Natural History Museum of Los Angeles where I work under the direction of Dr. Angel Valdes.

I am a plant cell biologist who has studied the chloroplasts of higher plants for many years. I've become very interested in the sacoglossans which retain algal chloroplasts, and am planning some research projects to examine how the slugs cooperate to provide the chloroplasts with the environment they need. I'm also planning to examine some of the algal species used by such slugs, to see if I can learn anything about what makes them so robust. Genera of interest include Vaucheria, Codium, Bryopsis, and Caulerpa. I am interested in talking with anyone who has first hand experience keeping sacoglossan species (especially Elysia spp.) in captivity, and with anyone who grows Vaucheria, Codium, Bryopsis or Caulerpa in their aquarium.

After working as PADI instructor in Thailand for almost 8 years I changed direction to work now as freelance (professional) Marine Wildlife Videographer. All started with the success of a few small documentaries. 'The most beautiful camouflages' in 2003 but most important 'The world of gastropods' which was awarded at many international UW filmfestivals worldwide. Including 'The golden fin' at the World festival for UW images in Antibes, France 2004, the most important festival worldwide. My interest goes mainly to filming the smallest creatures in the underwater world including of course all the magnificent nudibranchs. The most interesting nudi I found so far being Hypselodoris zebrina.

Mornington Peninsula,


I am a secondary Maths teacher with no background at all in Biology! I have been diving for nine years and through a friend who is mad about nudibranchs have decided that I adore them too. Most of my diving is under piers close to home - Frankston, Mornington, Rye, Portsea, Portarlington, St Leonards and local shore dives such as Linley Point in Mornington [Port Phillip Bay, Victoria, Australia]. I keep a very detailed dive log and like to sketch the nudibranchs as I find them. Through my ever increasing knowledge and my interest in all things marine, I've been able to develop and teach a unit of study in Marine Biology at my secondary school - Woodleigh School in Baxter Victoria. I belong to a small dive club - Aquatic Naturalists which meets monthly.

Back in the last century!, I had the pleasure of working with Tom Thompson and Bernard Picton at Bristol University for several years trying to clarify the taxonomy of the UK nudibranchs and making full use of SCUBA to aid collecting.

I've recently digitised all the nudi slides taken whilst preparing the publications from this earlier period. Having run through several research grants, I was eventually forced to get a job outside of academia but ended up running an Oceanography Department for a marine environmental company with projects worldwide. Unfortunately, I couldn't get paid for collecting slugs but with more storms and sea levels ever rising, we've never been busier in surveying and modelling the probable effects.
I remain a keen diver and nudibranch photographer visiting the Caribbean whenever possible but always remain envious of the Pacific divers who contribute so much to the Forum.

My research focuses on the nutritional and chemical ecology of marine plant-herbivore interactions, the ecology of mesograzers, and how prey traits affect the ecology and evolution of consumer feeding preferences in marine systems.

In Guam, some species of Volvatella recruit in large numbers every so often. I am currently working on some aspects of the feeding and chemical ecology of V. pyriformis (a specialist on Caulerpa sertularioides).

I am a postdoctoral research fellow studying chemical communication between Aplysia spp. Pheromone communication appears to be important to the success of these animals. One area of my research has led to the discovery that during the process of egg laying these animals release a blend of pheromones that attract other Aplysia, which results in aggregations of mating animals. We have characterised these pheromones in great detail. It's likely that a similar pheromonal system exists in other sea slugs.

For ca. 45 years observing and studying the marine invertebrates of the Red Sea, particularly the Gulf of Eilat (Aqaba Gulf). I earned my degrees studying the species diversity of an invertebrate community upon dead corals, while my doctorate dealt mainly with the consequences of chemical pollution on the growth and form (i.e. deformities) on the sea urchin Tripneustes gratilla elatensis (a Red Sea subspecies of this common sea urchin.
In between I gathered a large collection of mollusc shells, of ca 600 species. Lately I added more than 150 opistobranch species to a web guide for the Gulf mollusca, one of 7 webguides for other invertebrates. The guide and a personal site can be found under my website portal "dafni-sites".

After countless trips to the Caribbean, Nancy and Ron Sefton convinced me to try the Pacific. Now, I'm hopelessly 'Pacific'. My friends can't understand how I can travel alone to the opposite side of the planet, but they don't realized that all of us divers are one big family, reuniting at times in small groups. I loved the Solomon Islands, Papua New Guinea and Indonesia. I think the internet is the most amazing way of sharing our knowledge of these sea creatures, with voices from all over. Lately, I've been identifying Eric Cheng's photos from Rajah Ampat.

I specialise on mainly fossil heteropods and pteropods of Cainozoic age. I used to be a curator of the Dutch national Museum of Natural History (Palaeontology Department) at Leiden, the Netherlands, but currently I live a retired life in Malta, where I continue my research studying many samples from all over the world. Please have a look at my website to find further details about me and my work and a lot of info on holoplanktonic molluscs and their literature. I gratefully accept identification requests on fossil holoplanktonics ...

I grew up in the Marshall Islands and was trained in Hawaii as a biologist with special interest in West-Central Pacific nudibranchs. I spent several years at the Mid-Pacific Research Lab on Enewetak Atoll, but the lab closed due to lack of funding late in 1983. After spending so many years in the tropics, I found my blood too thin to spend much time in a temperate climate, and tropical jobs for nudi specialists were few. To earn a living, I switched to computer system administration as a day job -- but it really is just to support my addiction to compressed nitrogen delivered by scuba regulator. A still photographer for many years, I now spend most of my underwater time dragging around a video camera.

A year later we tried underwater photography, and ever since we are fully hooked on the little creatures. Ever more we find ourselves spending a whole dive on a couple of meters squared, while the sharks pass unseen behind our backs ...

Dear Dr.Bill
Let me inform you that, I am working on sea hares for 5 years now, I have got my M.Sc.on the biology and the chemical defence of sea hares collected from the Red Sea, EGYPT. I hope to continue in the same line in the study of the Doctoral degree.

My study includes:
1- Making a survey of sea hares collected from the Red sea, we identified six species, studied their taxonomic characters, presence, feeding habitat.
2- Detailed study of the anatomy, histology, histochemistry of the reproductive, digestive, nervous systems of Aplysia dactylomela, Dolabrifera dolabrifera also, with TEM and the SEM.
3- determined the LD50 of a crude extract of the digestive gland of the previous species and show its pharmacological characters.
4- isolation of two different algae from the filter chamber (Gyminodinum) from D. dolabrifera and the green algae Oedogonium from A. dactylomela.

Also, we derived some aliphatic terpenes from their digestve glands. I hope to study in my PHD the chemical defence.

My interest in sea slugs began when I first encountered them while learning to scuba dive as a teenager. Since then I have pursued a career in Marine Biology. My doctoral studies investigated the ecology of sea hares, specifically the costs and benefits to their fitness of feeding on chemically defended seaweeds. A particularly interesting part of this work was testing the long held belief that nothing eats sea hares. This was not the case for Aplysia parvula, many of which were consumed by fishes during experiments. My broader research interests include the ecology of marine molluscs and the role they play in temperate reef communities. Currently I am involved in the search for new antibiotics from marine molluscs as part of the marine bioprospecting initiative at the University of Wollongong.

An underwater photographer since the last dive of my first open water course (I actually bought a Nikonos V before getting my own dive gear!), I quickly became an avid (photographic) collector of ophistobranchs. In the beginning it was mainly because these are (often) colourful animals which don't swim away when you try to take their picture (though I had a nudibranch run fast enough to get away under a coral when I was rather narc'ed on my first 40m dive), but my interest quickly grew to encompass all aspects of opisthobranch zoology.

I am president of the Underwater Research Group of New South Wales [], where I'm infamous for my focus on nudibranchs. And when I'm not diving I lecture in finance at the University of Technology, Sydney.

I've been diving since 1994, and quite immediately started underwater photography. I have a Nikonos V with a 35mm lens, so it's difficult for me to get nudibranches. A friend lent me once his macro lens, but I found it difficult to use, since you have to choose to make a macro photo dive OR a normal photo dive (it takes a least 5 minutes to adapt the macro system on the 35mm lens).
If somebody has a solution, please contact me...

I've been a keen scuba diver since 1997 and in the last year have taken up underwater videography. Diving locations tend to be tropical - Indonesia being a favourite at the moment.

I am Assistant Curator of Mollusks at the Museum of Natural History of Los Angeles County. The Museum of Natural History of Los Angeles holds one of the largest collections of mollusks in the US, for the most part due to the impressive work of the retiring curator James McLean. Jim will continue working at the museum as an emeritus curator. The opisthobranch collection is small but contains a number of types and historically important specimens from the Panamic region and California. Several opisthobranch workers have been associated to the museum in one way or another, and they left material in the collections. My challenge is to increase the opisthobranch collection and at the same time keep the shell collection well-curated and growing.

*NOTE: Ángel's name should correctly be written Ángel Valdés. Unfortunately if I use accents, umlauts, diacritics etc, which are not used in English, then the name becomes invisible to search engines. If you are searching through the Forum for Ángel's messages search also from Angel Valdes as his name also appears in that anglicised format. This note applies to all other non-English names.

Hello, my name is Natasja and I am a very passionate scubadiver!!! I live in Belgium and except for the winter and the holidays I dive every weekend at the Oosterschelde in the Netherlands. And yes, even in these cold, dark waters we often have the pleasure to meet this lovely little creatures called nudibranchs. Unfortunately there is poor information to find in Dutch language. So I decided to start a webpage to put al the nudibranch information on I can possibly find in my own 'simple' words. Many of this information I find on this forum. Although I don't make exact copies and mix it with other information I find, I hope you don't mind too much Bill. As you will see, with every described species there's a link to your website.

I have been diving since 1975 and developed an early interest in all forms of marine life, particularly mollusca. From 1996-2000 I took part in survey work carried out by Operation Wallacea in the Tukang Besi Archipelago, SE Sulawesi, Indonesia. During this time we began work on building a species list of opisthobranchs to be found in the area and I continue to work on the data and photographs collected during that time. However my photographic interests extend beyond marine to all forms of wildlife and have been able to travel to a number of countries such as South Africa and Madagascar known for their spectacular land-based and airborne wildlife as well as marine.

I am currently Curator of Molluscs at the Museum and Art Gallery of the Northern Territory in Darwin. My research interests include the naming of sea slugs (nomenclature and taxonomy), their distributions (biogeography) and their relationships (phylogeny). I have been studying sea slugs for twenty-five years and have published nearly 70 scientific papers as well as popular books and articles in magazines. I am a diver and have conducted field trips throughout the tropical Pacific Ocean and south east Asia in search of opisthobranchs. My favourite nudibranch is Jason mirabilis and my favourite destination for nudibranchs is Norfolk Island.

I am engaged in research into the chemistry of natural products. I find nudibranchs fascinating animals both to observe and to study chemically. We rarely collect them as to do good chemical analyses we need about 10 gm dry weight of animals and normally we don't find many in any one place, so we leave them alone.

If you or your colleagues ever have any interesting animals that you think might be worthwhile us investigating just let me know.

I am a student of MSc. Programme of ZMT/ISATEC Univ. of Bremen, Germany. I come from Indonesia. I am interested in studying some aspect of the ecology of Phyllidididae (Nudibranchia) and perhaps use the biochemical compounds it contains in research that will be applied to inhibit settlement and overgrowth of biofouling organisms. I need some discussion about my topic research to get a good result. Perhaps I could also give some information about Nudibranchia in Indonesia.

I have been diving since 1994, mostly in South East Asia. On my first dive I already saw a blue pyjama nudibranch (probably Chromodoris annae ) and I was hooked. Since then I have been accused of only looking at the small critters and not seeing the large fish (mantas, eagle rays and sharks)!

On my website I have a large collection of nudibranch photos as well as slugs and sea shells -take a look!
