Bizarre, egg-laying mammal finally rediscovered after 60 years

More than sixty years after it was last recorded, an expedition team has rediscovered an iconic, egg-laying mammal in one of the most unexplored regions of the world. Attenborough's long-beaked echidna, named after famed broadcaster Sir David Attenborough, was captured for the first time in photos and video footage using remote trail cameras set up in the Cyclops Mountains of Indonesia's Papua Province.

Alongside the echidna's rediscovery, the expedition – a partnership between the University of Oxford, Indonesian NGO Yayasan Pelayanan Papua Nenda (YAPPENDA), Cenderawasih University (UNCEN), Papua BBKSDA, and the National Research and Innovation Agency of Indonesia (BRIN), Re:Wild – made many other remarkable finds. These included Mayr's honeyeater, a bird lost to science since 2008; an entirely new genus of tree-dwelling shrimp; countless new species of insects; and a previously unknown cave system. This was despite the difficulties posed by extremely inhospitable terrain, including venomous animals, blood-sucking leeches, malaria, earthquakes, and exhausting heat.

One of the world's most unusual mammals finally caught on film

Recorded by science only once in 1961, Attenborough's long-beaked echidna is a monotreme: an evolutionarily distinct group of egg-laying mammals that includes the platypus. This echidna species is so special because it is one of only five remaining species of monotremes, the sole guardians of this remarkable branch of the tree of life. Echidnas are notoriously difficult to find since they are nocturnal, live in burrows, and tend to be very shy. Attenborough's long-beaked echidna has never been recorded anywhere outside the Cyclops Mountains, and is currently classified as Critically Endangered on the IUCN Red List of Threatened Species.
