Understanding species' critical habitat requirements is crucial for effective conservation and management. However, such information can be challenging to obtain, particularly highly mobile, wide-ranging species as cetaceans. In the absence of systematic surveys, alternative economically viable methods are needed, use data collected from platforms opportunity, modelling techniques predict distribution in un-surveyed areas. The present study used by ecotourism other vessels opportunity investigate important habitats a small, poorly studied population bottlenose dolphins Port Phillip Bay, south-eastern Australia. Using 16 years dolphin sighting location data, an ensemble suitability model was built which physical factors influencing were identified. Results indicated that those areas close shipping channels coastlines with these primarily variation likelihood presence. relatively good performance suggests simple presence-background may sufficient predicting where limited. additional center Bay required further support this contention. Important features identified likely relate favorable foraging conditions they known provide feeding, breeding, spawning diverse range fish cephalopod prey species. results highlight importance affordable community-based collection, vessels, obtaining
