East Timor’s islands sit at a biogeographic crossroads where Sundaic and Australasian lineages meet, creating a compact but varied set of habitats from mangroves and lowland forest to upland ridges. That mix makes the country a rewarding place to study regional biodiversity and species with restricted ranges.
There are 50 East Timor’s native animals, ranging from the Asian Common Toad to the Yellow-crested Cockatoo. For each species, you’ll find below a concise row listing Scientific name, Endemic (Yes/No), and IUCN status to help you compare range and conservation concern — see the full list below.
How can I tell which species are unique to East Timor?
Check the Endemic (Yes/No) column: “Yes” indicates a species currently known only from East Timor. Use that with the Scientific name to cross-reference field guides and museum records; endemic species often need targeted habitat protection, so prioritizing them helps conservation planning.
What should I learn from the IUCN status column?
IUCN categories indicate global risk (e.g., Vulnerable, Endangered, Data Deficient). A threatened listing flags species that may need protection locally, while Data Deficient signals limited information — both warrant caution when observing or planning research, and consulting local conservation authorities is advised.
