The Vanadis worm, a type of large-eyed bristle worm or polychaeta, exhibits eyesight comparable to that of rodents, enabling it to see UV light, focus on small moving objects, and presumably use this ability for nocturnal activities such as mating and hunting. Remarkably, the worm’s eyes are exceptionally large, weighing about 20 times more than the rest of its head, highlighting their significance in the worm’s survival strategies. Credit: Michael Bok Researchers from the University of Copenhagen and Lund University are amazed by the discovery of a bristle worm that possesses eyesight as acute as that of mammals. They suspect that they may have a secretive language, only seen by their own species. The Vanadis bristle worm has eyes as big as millstones – relatively speaking. Indeed, if our eyes were proportionally as big as the ones of this Mediterranean marine worm, we would need a big sturdy wheelbarrow and brawny arms to lug around the extra 100kg. As a set, the worm’s eyes weigh about twenty times as much as the rest of the animal’s head and seem grotesquely out of place on this tiny and transparent marine critter. As if two giant, shiny red balloons have been strapped to its body. Vanadis bristle worms, also known as polychaetes, can be found around the Italian island of Ponza, just west of Naples. Like some of the island’s summertime partiers, the worms are nocturnal and out of sight when the sun is high in the sky. So what does this polychaete do with its walloping peepers after dark? And what are they good for? Neuro- and marine biologist Anders Garm from the University of Copenhagen’s Department of Biology couldn’t ignore the question. Setting other plans aside, the researcher felt compelled to dive in and try to find out. He was hooked as soon as his colleague Michael Bok at Lund University showed him a recording of the bristle worm. “Together, we set out to unravel the mystery of why a nearly invisible, transparent worm that feeds in the dead of night has evolved to acquire enormous eyes. As such, the first aim was to answer whether large eyes endow the worm with good vision,” says Michael Bok who together with Anders Garm, authors a new research article that does just that.[LINK] It turns out that the Vanadis’ eyesight is excellent and advanced. Research has demonstrated that this worm can use its eyes to see small objects and track their movements. “It’s really interesting because an ability like this is typically reserved for us vertebrates, along with arthropods (insects, spiders, etc.) and cephalopods (octopus, squid). This is the first time that such an advanced and detailed view has been demonstrated beyond these groups. In fact, our research has shown that the worm has outstanding vision. Its eyesight is on a par with that of mice or rats, despite being a relatively simple organism with a minuscule brain,” says Garm. This is what makes the worm’s eyes and extraordinary vision unique in the animal kingdom. And it was this combination of factors about the Vanadis bristle worm that really caught Anders Garm’s attention. The researcher’s work focuses on understanding how otherwise simple nervous systems can have very complex functions – which was definitely the case here. UV light and a secret language For now, the researchers are trying to find out what caused the worm to develop such good eyesight. The worms are transparent, except for their eyes, which need to register light to function. So they can’t be inherently transparent. That means that they come with evolutionary trade-offs. As becoming visible must have come at a cost to the Vanadis, something about the evolutionary benefits of its eyes must outweigh the consequences. Precisely what the worms gain remains unclear, particularly because they are nocturnal animals that tuck away during the day, when eyes usually work best. “No one has ever seen the worm during the day, so we don’t know where it hides. So, we cannot rule out that its eyes are used during the day as well. What we do know is that its most important activities, like finding food and mating, occur at night. So, it is likely that this is when its eyes are important,” says Anders Garm. Part of the explanation may be due to the fact that these worms see different wavelengths of light than we humans do. Their vision is geared to ultraviolet light, invisible to the human eye. And according to Garm, this may indicate that the purpose of its eyes is to see bioluminescent signals in the otherwise pitch-black nighttime sea. “We have a theory that the worms themselves are bioluminescent and communicate with each other via light. If you use normal blue or green light as bioluminescence, you also risk attracting predators. But if instead, the worm uses UV light, it will remain invisible to animals other than those of its own species. Therefore, our hypothesis is that they’ve developed sharp UV vision so as to have a secret language related to mating,” says Garm, who continues: “It may also be that they are on the lookout for UV bioluminescent prey. But regardless, it makes things truly exciting as UV bioluminescence has yet to be witnessed in any other animal. So, we hope to be able to present this as the first example,” says the researcher. Exciting for robotics research and evolutionary history As a result of the discovery, Anders Garm and his research colleagues have also started working with robotics researchers from the Maersk Mc-Kinney Møller Institute at the University of Southern Denmark (SDU) who find technological inspiration in biology. Together, they share a common goal of investigating whether it is possible to understand the mechanism behind these eyes well enough so as to translate it into technology. “Together with the robotics researchers, we are working to understand how animals with brains as simple as these can process all of the information that such large eyes are likely able to collect. This suggests that there are super smart ways to process information in their nervous system. And if we can detect these mechanisms mathematically, they could be integrated into computer chips and used to control robots,” explains Ander Garm. According to Garm, Vanadis’ eyes are also interesting with regards to evolutionary theory because they could help settle one of the heaviest academic debates surrounding the theory: Whether eyes have only evolved once – and evolved into every form that we know of today, or whether they have arisen several times, independently of one another, in evolutionary history. Vanadis’ eyes are built simply, but equipped with advanced functionality. At the same time, they have evolved in a relatively short evolutionarily time span of just a few million years. This means that they must have developed independently of, for example, human eyes, and that the development of vision, even with a high level of function, is possible in a relatively short time.

Unexpectedly, the scientists found a unique microbial population that can metabolize sulfur and atmospheric gases, resembling the microorganisms detected in deep-sea hydrothermal vents or geothermal hot springs. A team led by CU Boulder has uncovered a distinctive microbial community residing on the former island Hunga Tonga Hunga Ha’apai. In 2015, an underwater volcano in the South Pacific erupted, giving rise to the short-lived Hunga Tonga Hunga Ha’apai island. The University of Colorado Boulder and the Cooperative Institute for Research in Environmental Sciences (CIRES) spearheaded a research team that seized the uncommon chance to investigate the initial microbial inhabitants of a recently formed landmass. Surprisingly, they detected a unique microbial population that can metabolize sulfur and atmospheric gases, akin to organisms present in deep-sea hydrothermal vents or geothermal hot springs. “These types of volcanic eruptions happen all over the world, but they don’t usually produce islands. We had an incredibly unique opportunity,” said Nick Dragone, CIRES Ph.D. student and lead author of the study recently published in mBio. “No one had ever comprehensively studied the microorganisms on this type of island system at such an early stage before.” “Studying the microbes that first colonize islands provides a glimpse into the earliest stage of ecosystem development – before even plants and animals arrive,” said Noah Fierer, CIRES fellow, professor of ecology and evolutionary biology at CU Boulder and corresponding author on the study. A multi-institutional team of researchers on the ground collected soil samples from the island, then shipped them to CU Boulder’s campus. Dragone and Fierer could then extract and sequence DNA samples from the samples. Unexpected Microbial Discoveries “We didn’t see what we were expecting,” said Dragone. “We thought we’d see organisms you find when a glacier retreats, or cyanobacteria, more typical early colonizer species—but instead we found a unique group of bacteria that metabolize sulfur and atmospheric gases.” And that wasn’t the only unexpected twist in this work: On January 15, 2022, seven years after it formed, the volcano erupted again, obliterating the entire landmass in the largest volcanic explosion of the 21st century. The eruption completely wiped out the island and eliminated the option for the team to continue monitoring their site. “We were all expecting the island to stay,” said Dragone. “In fact, the week before the island exploded we were starting to plan a return trip.” However, the same fickle nature of the Hunga Tonga Hunga Ha’apai (HTHH) that made it explode also explains why the team found such a unique set of microbes on the island. Hunga Tonga was volcanically formed, like Hawaii. The Link Between Volcanic Origins and Unique Microbes “One of the reasons why we think we see these unique microbes is because of the properties associated with volcanic eruptions: lots of sulfur and hydrogen sulfide gas, which are likely fueling the unique taxa we found,” Dragone said. “The microbes were most similar to those found in hydrothermal vents, hot springs like Yellowstone, and other volcanic systems. Our best guess is the microbes came from those types of sources.” The expedition to HTHH required close collaboration with members of the government of the Kingdom of Tonga, who were willing to work with researchers to collect samples from land normally not visited by international guests. Coordination took years of work by collaborators at the Sea Education Association and NASA: a Tongan observer must approve and oversee any sample collection that takes place within the Kingdom. “This work brought in so many people from around the world, and we learned so much. We are of course disappointed that the island is gone, but now we have a lot of predictions about what happens when islands form,” said Dragone. “So if something formed again, we would love to go there and collect more data. We would have a game plan of how to study it.” Reference: “The Early Microbial Colonizers of a Short-Lived Volcanic Island in the Kingdom of Tonga” by Nicholas B. Dragone, Kerry Whittaker, Olivia M.

Credit: Luis Zelaya-Lainez, Vienna University of Technology Better understanding of this natural formation process offers potential for technical developments. A new interdisciplinary study led by molecular biologist Florian Raible from the Max Perutz Labs at the University of Vienna provides exciting insights into the bristles of the marine annelid worm Platynereis dumerilii. Specialized cells, so-called chaetoblasts, control the formation of the bristles. Their mode of operation is astonishingly similar to that of a technical 3D printer. The project is a collaboration with researchers from the University of Helsinki, Vienna University of Technology and Masaryk University in Brno. The study was recently published in the renowned journal Nature Communications. Nature’s 3D Printer: Bristle Worms Form Bristles Piece by Piece Chitin is the primary building material both for the exoskeleton of insects and for the bristles of bristle worms such as the marine annelid worm Platynereis dumerilii. However, the bristle worms have a somewhat softer chitin – the so-called beta chitin – which is particularly interesting for biomedical applications. The bristles allow the worms to move around in the water. How exactly the chitin is formed into distinct bristles has so far remained enigmatic. The new study now provides exciting insight into this special biogenesis. Florian Raible explains: “The process begins with the tip of the bristle, followed by the middle section and finally the base of the bristles. The finished parts are pushed further and further out of the body. In this development process, the important functional units are created one after the other, piece by piece, which is similar to 3D printing.” Comparison between “biological” (left) and “technological” 3D printing (right). Credit: Claudia Amort, Studio Amort Biogenesis of Bristles in Marine Worms A better understanding of processes such as these also holds potential for the development of future medical products or for the production of naturally degradable materials. Beta-chitin from the dorsal shell of squid, for example, is currently used as a raw material for the production of particularly well-tolerated wound dressings. “Perhaps in the future it will also be possible to use annelid cells to produce this material,” says Raible.

Credit: Ilya Belevich, University of Helsinki Role of Chaetoblasts in Chitin Formation The exact biological background to this: so-called chaetoblasts play a central role in this process. Chaetoblasts are specialized cells with long surface structures, so-called microvilli. These microvilli harbor a specific enzyme that the researches could show to be responsible for the formation of chitin, the material from which the bristles are ultimately made. The researchers’ results show a dynamic cell surface characterized by geometrically arranged microvilli. The individual microvilli have a similar function to the nozzles of a 3D printer. Florian Raible explains: “Our analysis suggests that the chitin is produced by the individual microvilli of the chaetoblast cell. The precise change in the number and shape of these microvilli over time is therefore the key to shaping the geometric structures of the individual bristles, such as individual teeth on the bristle tip, which are precise down to the sub-micrometer range.” The bristles usually develop within just two days and can have different shapes; depending on the worm’s stage of development, they are shorter or longer, more pointed or flatter.

Using their expertise in serial block-face scanning electron microscopy (SBF-SEM), the researchers investigated the arrangement of microvilli in the bristle formation process and proposed a 3D model for the synthesis of bristle formation. First author Kyojiro Ikeda from the University of Vienna explains: “Standard electron tomography is very labor-intensive, as the cutting of the samples and their examination in the electron microscope must be done manually. With this approach, however, we can reliably automate the analysis of thousands of layers.” The Raible group is currently working on improving the resolution of the observation in order to reveal even more details about bristle biogenesis.
