Branchs - Good Pictures Online
  • Branchs

Is there anything more beautiful and interesting than Opisthobranchs and Nudibranchs? They are my marine friends. I see their environment and learn about our amazing marine habitats through them and their perspective. A few years as an independent Branch Citizen Scientist in Queensland, Australia, have given me many insights under and above water.

Branch taxonomy (the naming of branchs) has become huge in my life, so much that I felt the need to become politically active about it. I went through various stages in my quest to find out what animals I am photographing. I went from trusting experts and pseudo experts, to becoming skeptical and even totally disillusioned, to now trying to be a role model and setting standards.

Following a single consistent taxonomy is important in order to have one common language. I am following WoRMS at the moment because it gives some pretty handy translation tools. All names used for my branchs match WoRMS and are checked on a regular basis. They might not match to what you are using, but they are what you maybe should be using. Please let me know if you find taxa (names) that don't match WoRMS and I will correct them as soon as possible. Try to do the same and be surprised how much you are starting to learn. Enjoy!

Taxonomy used: WoRMS (www.marinespecies.org)

Lists:

- all species in the (polyphyletic) infraclass Opisthobranchia presented here

- all true nudibranchia species in the suborder Dexiarchia (Aeolids) here

Opisthobranch Orders

Unidentified animals

Here I present a few animals that I photographed far away from my own research area. They are not my immediate priority to identify but I am curious to find out at some stage. Surely, there are a few easy identifications among them. There are even some non-opisthobranchs among them. Displaying unidentified animals (that I probably could know) illustrates that my claim is not to know it all. Every brancher will have such a list, hidden away or even thrown away. They have a purpose, namely to remind yourself of what you might come across again at some stage in your journey, be it in books or out in the field. I find such lists worth presenting and I found out that people like to dare a guess themselves. Quite a popular group for sure.

Heterobranch Egg Mass

Nudibranch and other heterobranch egg masses are often pieces of art. After all, egg masses belong to any serious biodiversity documentation effort. It is not always easy to assign an egg mass to a branch. Sometimes egg masses are highly visible while their parents display such a fantastic camouflage that you normally don't even see them when they are right next to their off-spring. Look through the egg masses and you'll notice that they offer many interesting questions. Why? Why the colour, why the shape, why the size, why the placement, why the timing? In my opinion, it is not coincidental but follows testable patterns. Last but not least, eggs are food and as such play immensely important roles in eco-systems.
