Taxonomic research on deep-sea macrofauna in the South China Sea using the Chinese deep-sea submersible Jiaolong

摘要

This paper reviews the taxonomic and biodiversity studies of deep-sea invertebrates in the South China Sea based on the samples collected by the Chinese manned deep-sea submersible Jiaolong.To date,6 new species have been described,including the sponges Lophophysema eversa,Saccocalyx microhexactin and Semperel­la jiaolongae as well as the crustaceans Uroptychus jiaolongae,Uroptychus spinulosus and Globospongicola ji­aolongi;some newly recorded species from the South China Sea have also been reported.The Bathymodiolus platifrons-Shinkaia crosnieri deep-sea cold seep community has been reported by Li(2015),as has the mito­chondrial genome of the glass sponge L.eversa by Zhang et al.(2016).The population structures of two domi­nant species,the shrimp Shinkaia crosnieri and the mussel Bathymodiolus platifrons,from the cold seep Bathy­modiolus platifrons-Shinkaia crosnieri community in the South China Sea and the hydrothermal vents in the Okinawa Trough,were compared using molecular analysis.The systematic position of the shrimp genus Globo­spongicola was discussed based on 16S rRNA gene sequences.
