“…Although no detailed faunal information is available at the seep off Pakistan, except one description of the vesicomyid clam Calyptogena makranensis, 65 photographs suggest that it is dominated by the Shinkaia squat lobsters and bathymodioline mussels. 23,66 It is possible that SCS and northern Indian Ocean seeps (plus any further undiscovered seeps between or around them) form a biogeographic region distinct from other western Pacific chemosynthetic communities.…”

“…20 In contrast, the seep communities at Haima and Site F, approximately 1150 km apart, are fairly distinct. For instance, the dominant species of bathymodioline mussels at Haima is G. haimaensis whereas that at Site F is G. platifrons; Archivesica marissinica, the dominant species of vesicomyid clam at Haima, has not been found at Site F. [20][21][22] In the Indian Ocean, two active seep areas, the Makran seep off Pakistan 23 and a seep off India 24,25 have been discovered, however, very little is known about their species composition.…”

<p>Deep-sea chemosynthetic communities, including hydrothermal vents and cold seeps, harbour hundreds of endemic species currently threatened by deep-sea mining and hydrocarbon extraction. The South China Sea (SCS), a semi-enclosed marginal sea with two well-investigated active seeps (Haima in the west and Site F in the east), provides an opportunity to understand the biogeography of chemosynthetic ecosystems. Here, we conducted extensive field surveys using Remotely Operated Vehicles (ROVs) and collected specimens for morphological observations, molecular barcoding, phylogenetic analysis, and stable isotope analysis. Cluster analyses were applied to reveal the community structure of vents and seeps in the Western Pacific and Northern Indian Ocean. A total of 65 species covering seven phyla and 14 classes have been identified from Haima, doubling the number of species reported previously. Among them, 35 species are currently known only from Haima. Stable isotope analysis shows a typical chemosynthesis-based biological community. Community structure analysis at the genus level clustered Haima with Site F, though the species compositions and dominance of two seeps are fairly distinct. Between the two active seeps in the SCS, the higher species richness and endemism at Haima are potentially due to multiple factors, including the unique environmental factors there and the geographic isolation in the northwestern corner of the SCS. Moreover, a similarity in community compositions at the genus level between seeps in the SCS and North Indian Ocean was revealed, potentially mediated by the Early Pliocene opening of the Indonesian islands and the strong westward Indonesia Throughflow. Given the ongoing gas hydrate exploration activities in the SCS, our results will contribute to establishing a global network of marine protected areas for chemosynthetic-based ecosystems. The rich and endemic biodiversity at Haima calls for policymakers to formulate regulations to conserve the unique biodiversity there.</p>

A tale of two tubeworms: taxonomy of vestimentiferans (Annelida: Siboglinidae) from the Mid-Cayman Spreading Centre

The vestimentiferan tubeworm genera Lamellibrachia and Escarpia inhabit deep-sea chemosynthesis-based ecosystems, such as seeps, hydrothermal vents and organic falls, and have wide distributions across the Pacific, Atlantic and Indian Oceans. In 2010–2012 during initial explorations of hydrothermal vents of the Mid-Cayman Spreading Centre (MCSC), both genera were found to co-occur at the Von Damm Vent Field (VDVF), a site characterised by diffuse flow, therefore resembling a ‘hydrothermal seep’. Here, we erect two new vestimentiferan tubeworm species from the VDVF, Lamellibrachia judigobini sp. nov. and Escarpia tritentaculata sp. nov. Lamellibrachia judigobini sp. nov. differs genetically and morphologically from other Lamellibrachia species, and has a range that extends across the Gulf of Mexico, MCSC, off Trinidad and Tobago, and Barbados, and also across both vents and seeps and 964–3304-m water depth. Escarpia tritentaculata sp. nov. is distinguished from other Escarpia species primarily based on morphology and is known only from vents of the MCSC at 2300-m depth. This study highlights the incredible habitat flexibility of a single Lamellibrachia species and the genus Escarpia, and historic biogeographic connections to the eastern Pacific for L. judigobini sp. nov. and the eastern Atlantic for E. tritentaculata sp. nov.
