The platypus is an amazing semi-aquatic mammal that is endemic to Eastern Australia and Tasmania. It is primarily nocturnal, living in creeks and rivers from cold highlands areas to tropical rainforests. Unfortunately platypus numbers appear to be declining due to habitat disruption, water extraction, pollution of waterways and illegal capture. PlatypusWatch needs your help to learn more about where platypus live and where they are disappearing. PlatypusWatch is a community-based program and involves members of the community undertaking platypus surveys, promoting and recording platypus sightings and assessing platypus habitats. This information is used to identify what education and conservation actions are needed to help protect this mammal.
