Cetacean observations in the Indian Ocean Sanctuary and the South China Sea, Mauritius to the Philippines, April 1999

Original provider: Marijke de Boer Dataset credits: Marijke de Boer Abstract: Information on cetaceans in the Indian Ocean Sanctuary and the South China Sea is summarized from a cruise carried out from 29 March to 17 April 1999. Ten species were positively identified: finless porpoise, pantropical spotted dolphin, spinner dolphin, sperm whale, melon-headed whale, pygmy killer whale, false killer whale, Cuvier’s beaked whale, Bryde’s whale and fin whale. Spotted dolphins, melon-headed and pygmy killer whales were sighted around the Island of Borneo and sightings of fin whales and a sperm whale west of the Balabac Strait suggest a possible migration route of these species between the South China Sea and the Sulu Sea. This is the first record of fin whales in the South China Sea.数据提供方： Marijke de Boer 数据集鸣谢： Marijke de Boer 摘要： 本数据集汇总了1999年3月29日至4月17日航次所采集的印度洋保护区与南海海域鲸类（cetaceans）相关信息。本次调查共明确鉴定出10个物种：江豚（finless porpoise）、热带斑海豚（pantropical spotted dolphin）、飞旋海豚（spinner dolphin）、抹香鲸（sperm whale）、瓜头鲸（melon-headed whale）、侏儒虎鲸（pygmy killer whale）、伪虎鲸（false killer whale）、柯氏喙鲸（Cuvier’s beaked whale）、布氏鲸（Bryde’s whale）及长须鲸（fin whale）。研究人员在婆罗洲周边海域观测到热带斑海豚、瓜头鲸与侏儒虎鲸；在巴拉巴克海峡以西海域发现长须鲸与抹香鲸的踪迹，这提示上述物种可能存在一条连接南海与苏禄海的迁徙通道。本记录为长须鲸在南海的首次正式记录。
