Biodiversity of Marine Animals in Hainan Island, China

海南岛是中国的第二大岛，位于中国的东南角，位于南中国海。该岛以拥有丰富的热带海洋动物而闻名，但由于政治和后勤问题，过去30年来没有进行过详细的调查。在东京国立科学馆海洋生物学家和青岛中科院海洋研究所的合作下，形成了一支联合力量。研究小组包括15名鱼类、甲壳类、棘皮和软体动物专家。在1997年2月中旬至3月中旬和11月中旬至12月初期间，通过使用水肺和拖网，在该岛南部和东部海岸捕获了沿海海洋动物。在南部海岸，收集的重点放在三亚地区，因为与岛上其他地区相比，珊瑚礁相对发达，尽管许多珊瑚礁被发现因港口建设和海滩开发而严重受损。利用小型底拖网渔船在三亚湾进行拖网作业。收集到的动物有鱼类、甲壳类、棘皮动物和软体动物。很大一部分标本是由小但具有分类学意义的标本组成的，其中包括许多中国首次记录的软体动物和鱼类，甚至是未描述的物种。

Hainan Island, the second largest island in China, is located at the south-east corner of China in the South China Sea. The island is well known for having rich tropical marine fauna but has not been surveyed in detail for the past 30 years because of political and logistic problems. A joint force was made under the cooperation between marine biologists of the National Science Museum, Tokyo, and the Institute of Oceanology, Academia Sinica, Qingdao. The research team included 15 specialists of fishes, crustaceans, echinoderms, and mollusks. In the periods of mid-Febrauary to mid-March and mid-November to early December in 1997, coastal marine animals were collected along the southern and eastern coasts of the island by using SCUBA and trawl. In the southern coast, a collecting emphasis was put on the Sanya area because coral reefs are relatively developed when compared to other areas in the island, although many coral reefs were found to be badly damaged by constructions of harbors and beach developments. Trawl collections were made in Sanya Bay by using a small bottom trawler. The collected animals were represented by fishes, crustaceans, echinoderms, and mollusks. Large parts of collection are composed of small but taxonomically interesting specimens which include many species of mollusks and fishes recorded for the first time from China and even undescribed species.
