Mutualism Great Partnership I Clownfish And Sea Anemones

(Symbiobiotic) Great Partnership: Clownfish and Sea Anemones Clownfish and sea anemones are a very famous partnership in the ocean. Clownfish take refuge in the anemone's tentacles, and they are immune to the anemone's venom. Instead, the clownfish's slime protects the anemone from herbivores and other potential hazards. This mutually beneficial relationship helps both parties survive and reproduce. The clownfish are safe under the protection of the anemone and can find food in the anemone's tentacles, while the anemone provides nutrients and protection from the clownfish. In addition to a mutually beneficial relationship, this partnership showcases the ecological diversity of nature. Through this cooperative approach, clownfish and sea anemones together form a micro-ecosystem that provides important ecological services to other organisms. What's amazing about this partnership is that the clownfish and sea anemone are so bonded, they're so interdependent on each other. If one of the creatures is threatened or suffers damage, the other will also be affected. This partnership shows us the interaction and interdependence between organisms, which has important implications for our protection and maintenance of the natural environment.

The study of coelenterates is now one of the most active fields of invertebrate zoology. There are many reasons for this, and not everyone would agree on them, but certain facts stand out fairly clearly. One of them is that many of the people who study coelenterates do so simply because they are interested in the animals for their own sake. This, however, would be true for other invertebrate groups and cannot by itself explain the current boom in coelenterate work. The main reasons for all this activity seem to lie in the considerable concentration of research effort and funding into three broad, general areas of biology: marine ecology, cellular-developmental biology and neurobiology, in all of which coelenterates have a key role to play. They are the dominant organisms, or are involved in an important way, in a variety of marine habitats, of which coral reefs are only one, and this automatically ensures their claims on the attention of ecologists and marine scientists. Secondly, the convenience of hydra and some other hydroids as experimental animals has long made them a natural choice for a variety of studies on growth, nutrition, symbiosis, morphogenesis and sundry aspects of cell biology. Finally, the phylogenetic position of the coelenterates as the lowest metazoans having a nervous system makes them uniquely interesting to those neurobiologists and behaviorists who hope to gain insights into the functioning of higher nervous systems by working up from the lowest level.

Anemonefishes and host sea anemones have one of the most well-known and iconic symbiotic relationships. The association between anemonefishes and host sea anemones has existed for at least 12 million years, however, this symbiotic relationship is quite rare, with the 28 different species of anemonefish living symbiotically with only ten out of over 1700 species of sea anemones. Furthermore, it is clear that both host sea anemones and anemonefishes glean significant fitness advantages from their symbiosis, including improved lifespan and potential reproductive success for anemonefishes, and increased nutrients and protection from predators for host sea anemones, however, the mechanism that enables this relationship. i.e., anemonefishes resistance to their toxic host sea anemone, remains unclear. Current research has focused solely on anemonefishes and the potential for their unique mucus layer to provide a form of protection against the toxins in their host sea anemone venom, with very little consideration for the role the host sea anemone itself may play in the establishment of this symbiosis. -- This thesis addresses this significant knowledge gap in our understanding of anemonefishes and host sea anemone symbiosis by exploring the relationship through the lens of the host sea anemone, via five research chapters. Through this body of research, I show that host sea anemones provide additional benefits to their anemonefish symbionts. Chapter 2 examined a previous hypothesis that the symbiotic relationship with toxic host sea anemones reduces the susceptibility of anemonefishes to ectoparasites. I found A. ocellaris living in symbiosis with a host sea anemone in the wild in Malaysia have a reduced ectoparasite load, and in an observational study in Malaysia and the Maldives there was no evidence that anemonefishes visited cleaning stations to remove ectoparasites, which provides further evidence that the sea anemone toxins may aid in protecting anemonefishes from ectoparasites. In Chapter 3 I quantified the nematocyte response of the host Entacmaea quadricolor to A. percula mucus. Acclimated and familiar A. percula trigger significantly fewer nematocytes than unacclimated A. percula, however, there are still some nematocytes fired at A. percula mucus while in association with the sea anemone. In chapter 4, I analysed the lipid and glycan profile of A. percula mucus to reveal that no significant change in lipids composition occurred in mucus collected before, during and after association with an E. quadricolor host, during an eight-week experiment. For the first time this work demonstrates a change of glycan profile in A. percula mucus, however this change only occurred after three weeks of association with E. quadricolor, and within 24 hrs of removal from the E. quadricolor anemone the anemonefish mucus layer had largely reverted back to its original glycan profile. Such a delay in the acclimation of the anemonefish mucus layer is unexpected and further study is needed to uncover the initial mechanism used by anemonefishes that enables them to enter the venomous tentacles of host sea anemones while their mucus layer adapts at the glycan level. In chapter 5, I used a proteotranscriptomics approach to reveal a comprehensive profile of the tentacle transcriptome which results in 2,736 proteins being present in venom from the most popular host anemone E. quadricolor. This work revealed that while E. quadricolor tentacles express RNA transcripts for numerous and diverse toxins only 10% of these are encoded as proteins present in the venom and that the venom mostly consists of mostly non-toxin proteins. In the final chapter, chapter 6, I used differential expression analysis to examine the role E. quadricolor itself plays a role in the establishment of their symbiotic relationship with A. percula, by analysing transcript and protein data from samples collected from E. quadricolor before and after hosting with an anemonefish pair. Specifically, I found that neurotoxin tentacle transcripts and venom proteins responsible for membrane damage, pore formation, and paralysis were downregulated during hosting with anemonefish. I also found that both natural venom inhibitor tentacle transcripts and proteins rich in IG-like domains were upregulated in the presence of anemonefish. -- Overall, this thesis demonstrates that host sea anemones play a much bigger role in the establishment and maintenance of their symbiosis with anemonefishes than previously thought, and by applying novel techniques to century-old questions, this thesis has redefined the research path to uncovering the mechanisms enabling the symbiotic relationship between host sea anemones and anemonefishes. Future research should consider the role of host sea anemone venom inhibitors as a resistance mechanism in symbiotic anemonefishes.

Over 1,000 species of sea anemone live at different depths of the world's oceans, and readers will be surprised to learn they all function without brains. Like other invertebrates, sea anemones use a simple nervous system to navigate the waters around them. This book examines this invertebrate's life cycle as well as some of the characteristics that make sea anemones so unique, for example their symbiotic relationship with clownfish. This is the perfect books for kids who are fascinated by nature's wonders.
