We review the species composition,distribution, and seasonal variation of fouling acorn barnacles in Chinese waters-from Bohai Sea and Yellow Sea to East and South China Seas. Thirty-two species of acorn barnacles were found, of which, the dominant species are Amphibalanus amphitrite, A. reticulatus, A. variegates, Balanus trigonus, Fistulobalanus kondakovi, Megabalanus tintinnabulum, Striatobalanus amaryllis, and Eurapha withersi in the fouling communities. A. amphitrite is the dominant species in the coastal waters of Bohai Sea and Yellow Sea and A. reticulatus is dominant in the East and South China Seas. The settlement period of fouling acorn barnacles is usually in summer and autumn. From north to south with the decrease of latitude, their settlement period obviously extends, even to the whole year, and the species number also increases.0ther environmental factors, such as salinity and distance from shore, also play an important role in the distribution of fouling acorn barnacles. 相似文献

Luidia Forbes (Paxillosida: Luidiidae) are common soft bottom sea stars with 49 described species. Because of substantial morphological diversity, the taxonomy of the genus is complex and hasn’t been resolved definitely. In order to resolve general taxonomic issues, and determine species boundaries and phylogenetic relationships within the genus Luidia, the sequences of cytochrome oxidase subunit I (COI) gene from 24 specimens of Luidia, belonging to eight taxa in Chinese waters, were studied. Three sequences of two species in genus Luidia from GenBank were used to analyze the phylogenetic relationships. The molecular phylogeny exhibited three main clades, each with strong bootstrap support: Clade A including Luidia quinaria from the Sea of Japan; Clade B including seven nominal species (L. quinaria von Martens, L. yesoensis Goto, L. changi Liu, Liao and Li, L. orientalis Fisher, L. avicularia Fisher, L. longispina Sladen and L. hardwicki Gray) from Chinese waters; and Clade C including L. maculata Müller & Troschel from Chinese waters. Our molecular phylogeny results support the morphological Quinaria-Group and Alternata-Group assigned by Döderlein. Seven nominal species we sampled do not exhibit genetic distances that are large enough to recognize them as separate species. Cryptic species may exist in’ Luidia quinaria’ from the Yellow Sea and the Sea of Japan. Meaningful morphological characters need further investigation in Luidia. 相似文献

Mucronella perforata was first discovered from Onagawa Bay, northern Honshu, Japan, in 1937 by Okada and Mawatari. It was reported from Hong Kong
and its neighboring waters and was referred to the genusHippopodina Levinsen, 1909 of the Family Hippopodinidae Levinsen, 1909 by Huang et al. (1990) and Huang (1994). According to the astogeny
of the species, both the ancestrula and its successor zooids have an ascus proximal to the orifice, and its hyperstomial ovicells
are imperforate, so it could not be a member of any known genus of the known families of the superfamily Schizoporelloidea
Jullien, 1883 in the infraorder Lepraliomorpha Gordon, 1989. The new genusPacificincola and the new family Pacificincolidae established respectively on the basis of reexaminations of the Chinese specimens obtained
from the southern Yellow Sea, the East China Sea and the northern South China Sea.Schizoporella insculpta Hincks, 1880 andHippoporina mexicana Soule, Soule et Chaney, 1995 have been referred to the new genus in the paper.

Eualus heterodactylus sp. nov., a new hippolytid shrimp from Chinese coast of the Yellow Sea （Crustacea,Decapoda, Caridea） 总被引：1，自引：1，他引：0
A new species from the caridean family Hippolytidae, Eualus heterodactylus sp. nov. is described and illustrated based on the specimens collected from Chinese coast of the Yellow Sea. The new species is a part of an informal species group characterized by the possession of epipods on the anterior three pairs of pereopods, and is distinguished from other species of this group by the dactyli of the third to fifth pereopods possessing distinctly stair-like flexor margins in males. 相似文献

This paper describes a new species of Nassarius from the South China Sea,which was recognized when re-sorting the collection of Nassariidae in the Marine Biological Museum,Chinese Academy of Sciences,Qingdao,China.The shells were collected during several investigations,including the National Comprehensive Oceanic Survey in 1958-1959,and the China-Vietnam Co-Investigation on Marine Resource of the Beibu Gulf during 1959-1962.The morphology of the shell and the radula places the new species of Nassarius within the subgenus Zeuxis.It is named Nassarius(Zeuxis) nanhaiensis sp.nov. 相似文献

In this paper,three deep-water species of the family Goniasteridae,Ceramaster misakiensis(Goto,1914),Nymphaster arthrocnemis Fisher,1913 and Pontioceramus grandis Fisher,1911,are recorded for the first time from Chinese waters based on collections deposited in the Marine Biological Museum,Chinese Academy of Sciences.The specimens examined were collected during the period 1956 to 1978 from the East China and South China Seas at depths of 184 to 472 m.Diagnosis,detailed figures,and the geographic distributions are provided.A revised list of Goniasteridae recorded from Chinese waters is proposed. 相似文献

Five galatheid squat lobster species belonging to four genera of two galatheid families are reported for the first time from Chinese waters, namely Lauriea simulata Macpherson and Robainas- Barcia, 2013, Phylladiorhynchus ikedai （Miyake and Baba, 1965）, Phylladiorhynchus integrirostris （Dana, 1852）, Babamunida sp., and Raymunida elegantissima （de Man, 1902）. The genera Lauriea Baba, 1971 and Babamunida Cabezas, Macpherson, and Machordom, 2008 have not previously been recorded from Chinese waters. 相似文献

We reviewed ampharetid genus Anobothrus Levinsen, 1884 in China seas based upon material deposited in the Marine Biological Museum of the Chinese Academy of Sciences (Qingdao). The genus includes A. glandularis (Hartmann-Schröder, 1965), A. gracilis (Malmgren, 1866), A. mironovi Jirkov, 2008 and A. nataliae (Jirkov, 2008). A. glandularis and A. mironovi are recorded for the first time in Chinese waters. A key to Chinese species of Anobothrus is given. 相似文献

Large scale northward expansion of warm water species Skeletonema tropicum (Bacillariophyceae) in China seas 总被引：2，自引：0，他引：2
Skeletonema tropicum is regarded as a species with an affinity to warm waters and it has never been reported in seas where temperatures drop below 11°C in winter. Previous studies in China reported that S. tropicum was restricted to subtropical and warm temperate seas (East and South China Seas), but the species was recently found during August cruises of 2009 and 2010 in Jiaozhou Bay, Yellow Sea, located several hundred kilometers to the north. Here, winter water temperatures often drop below 5°C. Identification of S. tropicum was confirmed under light and scanning electronic microscopes and maximum cell abundance in Jiaozhou Bay was estimated as 1.73×10 4 cell/L. This record of S. tropicum in Jiaozhou Bay represents a significant northward expansion in the geographic range of the species. Ship ballast water was identified as a possible carrier of S. tropicum from southern places along Chinese coastline, and in addition, thermal pollution from local power stations and seawater desalination plants may provide suitable conditions for species over-wintering. 相似文献

We measured the target strength (TS) of three commercial fish species: whitespotted spinefoot (Siganus canaliculatus), black porgy (Acanthopagrus schlegelii), and creek red bream (Lutjanus argentimaculatus), in the South China Sea. The TS of caged or tethered fish (n=76 total) was measured using a Simrad EY60 portable scientific echosounder at 120 kHz. We evaluated the relationship between TS and total length (TL, cm) for the three species. This is the first attempt to use split-beam acoustics to measure single-fish TS in the South China Sea by Chinese researchers. Our results will improve the accuracy and precision of acoustic abundance estimates of commercially important species and further the development of underwater acoustic survey techniques in fisheries in the South China Sea. 相似文献
