Abstract
Distribution and size variation of thecosomatous pteropods from the eastern Banda and western Arafura Sea (Indonesia) were studied during the southeast and northwest monsoon seasons in 1984 and 1985, respectively. During the SE monsoon the pteropod community presents evidence of a zoogeographic boundary located roughly along the Banda Arc, separating a Java and Banda Sea fauna in the west from a mixed imported Pacific and local upwelling fauna in the east. During the NW monsoon the boundary was not present and the Java and Banda Sea fauna, with Indian Ocean influences, was found thoughout the area. The observed patterns match the seasonal movements of watermasses in the area, and it is concluded that taxonomic composition and morphological data of the pteropod fauna are finetuned tracers of hydrography.
