About the Project

Understanding that it is not sufficient to study 'Singapore's marine mammals' or 'Indonesia's dolphins' or 'Malaysia's dugong' since these animals migrate across territorial boundaries such that 'our's' today is 'our neighbour's' tomorrow, we launched the South East Asia Wild Marine Mammal Survey (SEAWiMMS), a research project funded by Underwater World Singapore. SEAWiMMS aims to monitor the marine mammal population in South East Asia (about 30 different species) through a volunteer network and reporting system as well.
