Nudibranchs and sea slugs (“opisthobranchs”) are as beautiful as butterflies but appearance can be deceiving. Really they are dangerous warriors; of course for those of a similar stature…they come in all different colours, shapes and sizes. Like sharks, each species has a particular shape of teeth depending on what they feed on. Their behaviour and ecology are as diverse as their appearance and our knowledge of them is still poor. What we do know is that they are real chemical factories that might even hide secretes for the cure of deadly diseases such as cancer. Some have vivid coloration to show off how poisonous they are, others are so well camouflaged that even when knowing they are there, one cannot see them.

Sea slugs are probably the most interesting marine invertebrates on our planet (we are only a little biased!) and one of the most diverse groups. There are about 5000 species of sea slugs in the world and many remain undescribed to science. Until recently very little was known about the nudibranchs of Mozambique, but on-going research have found over 230 species only in Inhambane Province! From these almost all are new recordings for the country and about 30-40 are undescribed species. Some have never been seen or photographed before, which reminds us how little and limited is our understanding of the world. Bellow you can find updates on the research and findings of nudibranchs researchers including Yara Tibiriçá, Sabrina Brumme and Jenny Strömvoll.

Species+ Developed by CITES and CMS: Look up your favorite animal!

Source CITES Species+ is a new online resource providing comprehensive information on globally protected species. It includes all species covered by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and the Convention on the Conservation of Migratory Species of Wild Animals (CMS), as well as those included in the EU Wildlife Trade Regulations. Species+ can be accessed at What is Species+?… Read more »

Sea Slug Expedition – Support this idea, help to solve the puzzle!

In Zavora, every day in the field means a new discovery, a new piece for this puzzle and more entries to our database. In three years of study in a relatively small area, we have been able to find more species than is documented for the whole of Madagascar and the similar number as have been found in Tanzania. Our research has so far been… Read more »
