Western Long-beaked Echidna

Zaglossus bruijnii

Critically Endangered

At extremely high risk of imminent extinction in the wild.

Spotted something wrong?

The western long-beaked echidna is a monotreme, one of only five living mammals that lay eggs. It inhabits the mountains of West Papua, in Indonesia, and feeds almost exclusively on earthworms, which it hooks with the barbs on its tongue. Its body is covered in spines mixed with dense fur, and it has a long snout curving downwards. It is critically endangered through hunting and forest loss, and for decades there was no confirmed record of the species.

Fun facts

  • In November 2023 a scientific expedition filmed it alive in the Cyclops Mountains after more than sixty years without a confirmed record.
  • Like all monotremes, the female lays a leathery egg that she incubates in a temporary pouch and then feeds the young on milk that seeps through the pores of her skin, since she has no teats.
