Attenborough's Long-beaked Echidna
62 years of silence — then a camera trap in the world's least explored mountains
No confirmed photograph exists
Location
Cyclops Mountains, Papua, Indonesia
Overview
Attenborough's long-beaked echidna is one of five surviving monotremes — mammals that lay eggs, like the platypus. It has the spines of a hedgehog, the beak of an anteater, and the digging limbs of a mole. The last known scientific specimen was collected in the Cyclops Mountains of Papua in 1961 by Dutch botanist Pieter van Royen. For 62 years, the species existed only in museum drawers. Then, in 2023, an Oxford University expedition deploying camera traps throughout the Cyclops Mountains captured a clear image. It is named after Sir David Attenborough.
Why haven't we found it?
The Cyclops Mountains are considered among the most poorly explored mountain ranges on Earth. They rise sharply from the coastal plain near Jayapura with almost no road access, dense vegetation, and extreme terrain. Even the 2023 expedition that found the animal spent weeks in the field and retrieved only the one camera trap image. Echidnas are also naturally elusive — they move slowly but are nocturnal, solitary, and spend daylight hours buried under roots and leaf litter.
How it was found
- 1
The 2023 Oxford camera trap image shows a healthy adult animal, confirming the species is alive and at least one individual is using the area.
- 2
Local Papuan communities in the Cyclops foothills have oral traditions describing the animal — known locally as 'payangko' — as present within living memory.
- 3
The Cyclops range is a protected nature reserve, limiting some hunting pressure, though enforcement is difficult.
Things worth knowing
- 1
Monotremes are the most ancient surviving mammal lineage, branching from all other mammals over 200 million years ago. The long-beaked echidna is essentially unchanged from fossils of that era.
- 2
Echidnas can lower their body temperature to near-ambient and enter a torpor state when food is scarce, surviving conditions that would kill most mammals of similar size.
- 3
They have no teeth. The long beak is an electroreceptor — it can detect the faint electrical fields generated by earthworms and insects buried underground, the same sense the platypus uses in water.

The 2023 rediscovery expedition was led by Dr James Kempton of Oxford. The camera trap that captured the image was positioned based on soil disturbance patterns — echidna snout marks in the forest floor — detected during the field survey.

Sir David Attenborough commented on the rediscovery, calling it 'the most exciting news' — the species was named after him in 1998, when he was 72, during what was thought to be its permanent disappearance.
