In 2001, <str<strong>on</strong>g>the</str<strong>on</strong>g> first l<strong>on</strong>g-term study <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g> Indo-Pacificbottlenose dolphin in Chinese waters was launched with <str<strong>on</strong>g>the</str<strong>on</strong>g> main goal <str<strong>on</strong>g>of</str<strong>on</strong>g> increasing ourknowledge <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g> biology <str<strong>on</strong>g>of</str<strong>on</strong>g> this poorly known coastal species (which has experienced substantialexploitati<strong>on</strong> in <str<strong>on</strong>g>the</str<strong>on</strong>g> recent past). Data were collected from a small research vessel <strong>and</strong> threel<strong>and</strong>-based platforms. By combining data from 2001 <strong>and</strong> 2000, some preliminary but importantinsights into <str<strong>on</strong>g>the</str<strong>on</strong>g>se dolphins were gained. <strong>The</strong> preliminary estimate <str<strong>on</strong>g>of</str<strong>on</strong>g> abundance <strong>and</strong> density <str<strong>on</strong>g>of</str<strong>on</strong>g><str<strong>on</strong>g>the</str<strong>on</strong>g>se dolphins in sou<str<strong>on</strong>g>the</str<strong>on</strong>g>rn Taiwan was very low (about 24 individuals in <str<strong>on</strong>g>the</str<strong>on</strong>g> study area <str<strong>on</strong>g>of</str<strong>on</strong>g> about85 km 2 ). Of <str<strong>on</strong>g>the</str<strong>on</strong>g>se dolphins, nine individuals were identified from distinct characteristics (e.g.,shape, scars, pigmentati<strong>on</strong>) <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g>ir dorsal fins.
