Lead-authored paper published in Zootaxa today! This paper describes Astyris thermophilus Chen, Watanabe, Araya, 2017, the first Columbellidae species discovered from deep-sea hydrothermal vent ecosystems. Its Japanese name literally means "columbellid from the underworld". It was found at the Natsu site, Iheya North hydrothermal field, Okinawa Trough, just shy of 1100m depth. http://www.mapress.com/j/zt/article/view/zootaxa.4363.4.13<br /> <br /> Please let me know if you would like to have a PDF copy. <br /> <br /> Chen C*, Watanabe HK, Araya JF (2017).

New lead-authored paper, announcing the discovery of two new peltospirid vent snails, has been published in the peer-reviewed Open Access journal Frontiers in Marine Science! Read for free here: https://doi.org/10.3389/fmars.2017.00392<br /> <br /> This paper describes two new species of small gastropods, belonging to the hydrothermal vent endemic family Peltospiridae, from the Longqi hydrothermal vent field (~2785 m deep) on the Southwestern Indian Ridge, Indian Ocean; a new genus was erected to house one of them. The descriptions are based on shell (protoconch, teleoconch, periostracum, shell microstructure), radula, as well as anatomical characters. Lirapex politus Chen et al., 2017 (~4.5 mm shell height) is the first Indian Ocean representative of genus Lirapex which is also known from eastern Pacific and mid-Atalantic vents, and differs from the other known congeners by its lack of obvious axial sculpture (hence ‘politus’, smooth), as well as a narrower umbilicus and the final 0.5 whorl of the teleoconch being less detached. Dracogyra subfuscus Chen et al., 2017 (~7 mm shell diameter) is a depressed, globular, coiled peltospirid with a dark periostracum; the genus Dracogyra Chen et al., 2017 was established for this species. It is most similar to Depressigyra globulus Warén & Bouchet, 1989 known from the eastern Pacific, but easily separated from it by a lack of basal notch in the aperture and a more depressed shell with narrower umbilicus. Furthermore, the radula of D. subfuscus is highly characteristic with the central tooth being very wide and compressed. A Bayesian phylogeny using the mitochondrial COI barcoding gene confirmed the placement of the two new species in clade Neomphalina and family Peltospiridae. The two new species co-occur with two giant holobiont peltospirids including the scaly-foot Chrysomallon squamiferum Chen et al., 2015 and Gigantopelta aegis Chen et al., 2015, and are sometimes found on their body surface. The two new species do not host endosymbiotic bacteria and gut contents suggest that they probably feed on microbial film on chimney surfaces, as well as epibionts of the two larger peltospirids. <br /> <br /> Chen C*, Zhou Y, Wang C, Copley JT (2017).

Lead-authored paper reporting the unexpected discovery of two very rare snails in two new hydrothermal vent sites is now published in the peer-reviewed Open Access journal PeerJ! Read for free at: https://peerj.com/articles/4121/<br /> <br /> In this paper, we report the discovery of two very rare gastropods – the calliostomatid Otukaia ikukoae Sakurai, 1994 and the muricid Abyssotrophon soyoae (Okutani, 1959) in newly located hydrothermal vent sites in the Okinawa Trough, Japan. One of the two new sites is named the “Fukai” site after the poisonous forest of the same name in the Studio Ghibli film “Nausicaä of the Valley of the Wind” (1984)! The discovery of these snails represent the second record of Calliostomatidae and the third Muricidae from vents, and also represent range extensions of both species to the southwest, by about 700 km in the case of O. ikukoae. Based on radular characteristics, O. ikukoae is returned to genus Otukaia from Tristichotrochus. Although this is the first time either species are observed in their natural habitat, both are considered to be occasional invaders of vent ecosystems from surrounding regular sea bottom and not vent endemics given their other records from non-vent environment as well as the fact that they were found in weak diffuse flow venting areas and not focused venting areas. Nevertheless, it is clear that they are able to tolerate, to a certain extent, environmental stresses associated with vents (e.g., raised heavy metal and hydrogen sulfide concentrations). This enables them to access to rich food supplies supported by chemosynthesis primary production, and suggest that vent periphery likely play a key role in the evolution of biological adaptation to hydrothermal vent environment. <br /> <br /> Chen C*, Watanabe HK, Miyazaki J, Kawagucci S (2017).

Lead-authored paper on shallow water hydrothermal vent molluscs published in journal Marine Biodiversity! Read online for free: http://rdcu.be/wKVR<br /> <br /> This paper reports diversity of molluscs inhabiting shallow water (10-30m deep only!) hydrothermal vent ecosystem off Kueishan Island, Taiwan. Unlike deep-sea hydrothermal vents no endemic molluscs were found, and the species present were a subset of species present in surrounding areas that are apprently able to tolerate the 'extreme' environment. We report a total of 13 core species including 12 gastropods and one chiton, and discuss their ecology at the shallow vents. <br /> <br /> Please let me know if you would like to have a PDF copy. <br /> <br /> Chen C*, Chan T-Y, Chan BKK (2017).

A co-authored paper about the mechanism of symbiosis in a deep-sea vent crustacean is now published in the journal "Deep Sea Research Part I": https://authors.elsevier.com/c/1Vm3k3RueHIHRB . <br /> <br /> Shinkaia crosnieri Baba & Williams, 1998 is a vent-endemic squat lobster with dense setae / hair on its ventral surface. Much like its distant (convergently evolved) cousin, the "yeti-crab" Kiwa, these setae are full of epibiotic bacteria. Recently, S. crosnieri became the first vent animal where the nutritional reliance on epibiotic bacteria was experimentally demonstrated. In this study, we take a step further and show that S. crosnieri actively utilises and produces water current that significantly increases the productivity (chemosynthetic activity) of its epibionts. This means the squat lobster is actively cultivating / farming its own food -- the first example of such behavioural adaptation demonstrated among epibiont-hosting animals inhabiting chemosynthetic ecosystems.<br /> <br /> Through a series of experiments measuring the rate of chemosynthesis (sulfide consumption rate), it was revealed that the rate in epibionts significantly increased when water current was produced. Then, living S. crosnieri individuals were shown to produce an endogenous water flow to the ventral setae through elegant current visualisation using fluorescent particles. Finally, behavioral experiment indicated that S. crosnieri likely exhibit rheotaxis in its natural habitat, meaning it uses existing water current in addition to self-generated ones to increase the productivity of its epibionts = food.<br /> <br /> Watsuji T, Tsubaki R, Chen C, Nagai Y, Nakagawa S, Yamamoto M, Nishiura D, Toyofuku T, Takai K (2017).

New co-authored paper published in the journal "Polar Biology"! The article can be read for free via the following link: http://rdcu.be/tWBe . <br /> <br /> In this paper, we characterised microbes associated with the recently discovered Antarctic vent snail Gigantopelta chessoia Chen et al., 2015. It has been known that this snail hosts endosymbionts in an much enlarged oesophageal gland, but the details about the symbiont's phylogenetic position has not been published. We show that the endosymbiont is a Gammaproteobacteria related to sulfur-oxidising bacteria from cold seeps and other animals living in chemosynthetic ecosystems. Also revealed is a more diverse epibiont community on the gill surface, including members belonging to Gamma, Epsilon and Deltaproteobacteria. Interestingly, the endosymbiont Gammaproteobacteria strain was also found on the gill surface but not in the surrounding water column. Given that juveniles of this species is regularly recovered from within the adults' mantle cavity, this suggests they may acquire the symbionts directly from the gills of adult snails. <br /> <br /> Heywood JL, Chen C, Pearce DA, Linse K (2017).

New co-authored paper (with Shinsuke Kawagucci and other colleagues) is now officially published in the Open Access journal Frontiers in Earth Sciences! Available from: http://journal.frontiersin.org/article/10.3389/feart.2017.00045/full/<br /> <br /> Long story short, we developed a new water sampler for collecting hydrothermal fluid and other geofluids in the deep-sea. This new sampler, the "WHATS-III", is capable of pressure-tight, flow-through sampling of four independent geofluids per submersible dive. We also present real data collected during field tests carried out in hydrothermal vents of the Indian Ocean and Okinawa Trough. <br /> <br /> Miyazaki J, Makabe A, Matsui Y, Ebina N, Tsutsumi S, Ishibashi J, Chen C, Kaneko S, Takai K, Kawagucci S (2017).

New co-authored paper (with Yanjie Zhang, Jin Sun, Hiromi Watanabe-Kayama and others) on the adaptation and evolution of deep-sea vent/seep scale worms (polynoid polychaetes) published in Scientific Reports! The article is open access and free to read here: http://www.nature.com/articles/srep46205<br /> <br /> Scale worms inhabit a great variety of environments ranging from very shallow water down to kilometres deep and are often an important member of chemosynthetic ecosystems such as vents, often living in close proximity to hot black smokers. In this study, we sequenced the transcriptomes of two deep-sea scale worms inhabiting hydrothermal vents and hydrocarbon seeps and one shallow water counterpart that was rather closely related. By comparing the three transcriptomes, we were able to elucidate selective amino acid usage, positively selected genes, highly expressed genes, and potentially duplicated genes, thereby shedding light on how the scale worms evolved to become successful members of deep-sea chemosynthetic communities. These are the first deep-sea scale worm transcriptomes ever reported. <br /> <br /> Most significant among our findings was the significance of genes related to haemoglobin. The two deep-sea polynoids chosen for this study, in the genera Branchipolynoe and Lepidonotopodium, are shown to have adopted different yet equally effective ways to cope with the oxygen-poor chemosynthetic ecosystems. Branchipolynoe rapidly evolved a novel tetra-domain haemoglobin which is highly effective in oxygen transport, whereas Lepidonotopodium increased the expression levels of standard single-domain haemoglobin to four times as high as Branchipolynoe. These results indicate that dealing with hypoxic environment is a key element in becoming successful in deep-sea vents and seeps. <br /> <br /> PS. I know this is not a mollusc paper, but I am interested in all cool animals especially when they have evolved key adaptations to live in weird environments! And the importance of haemoglobin is not limited to scale worms, but also applies to molluscs. <br /> <br /> Zhang Y [Yanjie], Sun J, Chen C, Watanabe HK, Feng D, Zhang Y [Yu], Chiu JMY, Qian P-Y, Qiu J-W (2017).

New paper dealing with a 'cryptic species complex' of chitons published in Marine Biodiversity! Open access, please read here: http://bit.ly/2okQQ56<br /> <br /> In this work, we present a case study of a total-evidence approach to resolving difficult and perplexing 'cryptic species complexes'. A Pacific shallow water polyplacophoran mollusc (chiton) Leptochiton rugatus (Carpenter in Pilsbry, 1892) is supposed to have a very wide range from Japan to Baja California, but has been previously suggested to comprise several cryptic species. Our genetic haplotype network using specimens across the range revealed four discrete clusters. Most strikingly, the haplotype of L. rugatus sensu stricto (California to Baja California) was very different in structure from that of the cluster ranging from the panhandle of Alaska to Oregon. The latter was found to have extremely high side fidelity and patchy distribution, and we present evidence that it is likely a brooder. The difference in life-history strategies between these two clusters account for the differences in their genetic structure. Although morphological differences were observed, these were minor and insufficient to guarantee each as species-level lineages alone. Only with the difference in life-history strategy could they be confidently recognised as separate species, the latter we described as L. cascadiensis sp. nov. after the Cascadia costal bioregion which it inhabits. <br /> <br /> Things without names are difficult to rationalise, and are difficult to conserve; assigning names to species is therefore critical to understanding and conserving biodiversity.This study shows that combining evidence from molecules, morphology, and importantly life-history, is key to untangling 'cryptic species complexes' which have become increasingly discovered in the recent years. The take-home message: if you want to solve cryptic species problems, don't forget to look at their way of life!<br /> <br /> This is my first time getting involved with describing a chiton, yay!

New co-authored paper published today in The Nautilus! Read: http://bit.ly/2o07dEe <br /> <br /> We discuss the potential impacts of deep-sea mining to molluscan biodiversity, especially with regards to exploiting active hydrothermal sulfide deposits. Take the famous scaly-foot gastropod Chrysomallon squamiferum as an example – it is only known from three hydrothermal vents in the Indian Ocean, each around 0.003 sq km or half the size of a football field. Two of the three scaly-foot sites are already under active mining exploration licenses from the International Seabed Authority (ISA), to China (2011-2026) and Germany (2015-2030); the last one is in the Mauritius exclusive economic zone and therefore not under ISA jurisdiction. In fact, only 37 vent sites have been detected (4 actually visited) in the Indian Ocean (area approx.. 73,550,000 sq km) and their total area adds up to a mere 0.27 sq km (check out the infographics)! Many of these are also within the areas licenced for mining. These explorations are due to begin very soon and no conservation measures are in place or proposed, whereas many terrestrial mollusks such as the two-lipped door snail Alinda biplicata have extensive reserves dedicated to their conservation. Economic and political pressures to exploit deep-sea vents are advancing far quicker than our scientific understanding of these ecosystems that unique animals such as the scaly-foot call home, putting them at risk. Conservation measures for vent animals are urgently needed, and seem warranted given their tiny, disjunct areas of distribution. <br /> <br /> Please let me know if you would like a PDF copy, as usual. <br /> <br /> The original idea of this work was presented at the “Mollusks in Peril” 2016 Forum at the Bailey-Matthews National Shell Museum. <br /> <br /> Sigwart JS, Chen C, Marsh L (2017).

New first-authored paper published in BMC Evolutionary Biology ( http://bit.ly/3DGIGANTO ) reveals that two neomphaline hydrothermal vent gastropods, Gigantopelta and the 'scaly-foot' Chrysomallon, convergently evolved the peculiar adaptation of housing endosymbiotic bacteria in their much enlarged oesophageal gland. We first confirmed the existence of endosymbionts in Gigantopelta using Transmision Electron Microscopy (TEM), and then carried out serial sectioning and 3D reconstruction for a juvenile specimen of Gigantopelta chessoia along with dissections of the adult. These revealed many key anatomical differences with the 'scaly-foot gastropod' pointing towards two independent origins of a similar way of life, confirmed by a 5-gene phylogenetic reconstruction clearly showing that the two are not sister within the known members of Peltospiridae. By comparing Gigantopelta and Chrysomallon, we show that metazoans are capable of rapidly and repeatedly evolving equivalent anatomical adaptations and close-knit relationships with chemoautotrophic bacteria, achieving the same end-product through parallel evolutionary trajectories.<br /> <br /> The paper is open access and available freely: http://bmcevolbiol.biomedcentral.com/articles/10.1186/s12862-017-0917-z<br /> <br /> We also included an interactive 3D anatomical model of Gigantopelta, you only need a PDF reader to play around with it!

A new first-authored paper (http://bit.ly/2g4qYmQ) has been published in Journal of the Marine Biological Association of the United Kingdom! This paper describes Provanna cingulata n. sp., from Shinkai Seep Field, a serpentinisation-hosted ecosystem 5700 m deep in the Mariana Trench. It is the deepest and largest member of genus Provanna, which is endemic to chemosynthetic ecosystems. Unlike most Provanna species which either have prominent lattice sculpture or completely smooth, this species is characterised by prominent spiral sculpture but lacking in axial sculpture.

A new paper lead-authored by myself has been published today in Molluscan Research today ( http://bit.ly/Chen2016a )! The paper describeds a new species of Desbruyeresia (Gastropoda: Provannidae), Desbruyeresia chamorrensis Chen, Ogura & Okutani in Chen et al., 2016. The family Provannidae is only known from chemosynthetic ecosystems, and genus Desbruyeresia was so far restricted to hydrothermal vents. The present new species, however, was discovered from an alkaline serpentinite-hosted seep more than 2900m deep on the South Chamorro Seamount (13°47’N, 146°00’E), southeastern Mariana Forearc. It is a deposit feeder and only three specimens have been collected so far. It is distinguished from all other described congeners by having much more numerous (17–20) axial ribs on the teleoconch and a broad shell for the genus (shell width to height ratio 0.6–0.65). It was a great pleasure working with the eminent Japanese malacologist Prof. Takashi Okutani during the course of this project.

New lead-authored paper published in the Zoological Journal of the Linnean Society! This is the description of a brand new genus of large deep-sea hydrothermal vent snail, Gigantopelta. Two new species are described, G. chessoia from the Antarctic vents in the East Scotia Ridge and G. aegis from the Southwest Indian Ridge. Both are from bathyal depths exceeding -2500m, and are powered by chemosynthetic endosymbiont bacteria housed in the esophageal gland. They belong to the "hot-vent" family Peltospiridae in the clade Neomphalina, and being even larger (slightly, up to 45.7mm) than the 'scaly-foot gastropod', these are the largest neomphalines known to date. Hence "giganto", meaning "giant", derived from "Gigantes", the giants in Greek mythology. G. chessoia is a dominant species in East Scotia Ridge vents, the only truly Antarctic vents well-explored to date. G. aegis is especially interesting because both the shell and operculum are overlaid by a thick layer of iron oxide (i.e., rust), and thus it is another iron-armoured vent gastropod like the 'scaly-foot'. The operculum, especially, is so thickened that it is almost like a calcified one of a turbinid; hence the name "aegis", which refers to the mythical shield of Zeus and Athena. <br /> <br /> Please do let me know if you would like a copy of the full-text in PDF 🙂<br /> <br /> Chen C, Linse K, Roterman CN, Copley JT, Rogers AD (2015).

A co-authored paper has just been published on the online journal PLOS ONE (http://bit.ly/1DCnBXW)! What happens to local ecosystem if you make an artificial hydrothermal vent by deep-sea drilling? We investigated this in Okinawa Trough, Japan by monitoring the benthic area across a 40-months period after a drilling event. Through quantifying the visible changes in benthos fauna we found many interesting facts such as Shinkaia crosnieri squat lobsters are able to literally migrate on foot from nearby vents, and also showed how various vent animals colonise the new habitat in this area. This is among the first research to elucidate the initial formation processes of deep-sea hydrothermal vent ecosystems, and provides key information for future ecosystem assessment in the event of deep-sea mining, for example. This research was done in collaboration with JAMSTEC in Japan and was lead-authored by Dr. Ryota Nakajima from there.
