Eastern Long-beaked Echidna Zaglossus bartoni
Status: Vulnerable
Location: Endemic to the highlands of Papua New Guinea.
The Eastern long-beaked echidna Zaglossus bartoni is one of the planet’s most extraordinary mammals—a living relic from the dawn of mammalian evolution. Found only in the rugged, remote mountains of New Guinea, this remarkable creature is genetically and physically unlike any other animal alive today. Their existence bridges ancient evolutionary traits with the survival needs of modern species, representing a fascinating link to the distant past.
Tragically, these rare monotremes face the threat of extinction due to hunting and habitat loss for palm oil, timber and gold mining. Support indigenous-led conservation and fight for their survival. Use your wallet as a weapon and #BoycottPalmOil #Boycott4Wildlife.

Eastern Long-beaked #Echidnas are rare egg-laying #mammals 🥚🦔 They are a prehistoric fever dream with a tube-like beak and hedgehog like spines. Help them survive in #NewGuinea 🇵🇬 when you #BoycottPalmOil 🌴🪔🤮🙊🚫 #Boycott4Wildlife @palmoildetect https://palmoildetectives.com/2021/02/03/eastern-long-beaked-echidna-zaglossus-bartoni/
Appearance and Behaviour
The Eastern long-beaked echidna looks like something out of a prehistoric dream. They weigh between 5 and 9 kilograms (10–20 pounds) and are covered in coarse fur interspersed with hedgehog-like spines that offer protection from predators. Their most distinctive feature is their elongated, tube-like beak, which is a marvel of evolutionary adaptation. Unlike most mammals, they lack teeth and a conventional jaw; instead, their beak is lined with electro-receptors, allowing them to detect the faintest electrical signals from underground prey. This unique “beak” functions as a tool for slurping up earthworms and insects, much like a child sucking up spaghetti.
These shy creatures are primarily nocturnal, spending their days hidden in burrows or dense undergrowth. A remarkable trait observed is their limb preference during digging activities, with some individuals demonstrating clear “handedness” (Limb Preferences in Monotremes, 2015).
Their gait and behaviour further highlight their primitive charm. With a shuffling, deliberate walk, they use powerful claws to dig through soil and leaf litter. Despite their armour-like exterior and prehistoric lineage, these echidnas are docile and shy, avoiding confrontation whenever possible. Each movement and adaptation offers a glimpse into a time when mammals first emerged, making them not just a species, but a living connection to the evolutionary history of life on Earth.
Threats
IUCN Status: Vulnerable
Palm oil, timber and gold mining deforestation:
The destruction of montane forests due to timber deforestation, palm oil monoculture, and gold mining has significantly reduced the Eastern long-beaked echidna’s habitat (IUCN Red List, 2021).
Hunting Pressures:
These echidnas are heavily hunted for bushmeat, even in areas where hunting them is prohibited, posing a critical threat to their survival (IUCN Red List, 2021).
Across New Guinea, more than 800 tribal cultures rely on hunting for protein, with echidnas often targeted as a prized food source (Mongabay, 2015).
Habitat Fragmentation:
Habitat fragmentation from human activities isolates populations, reducing genetic diversity and limiting their ability to adapt to environmental changes (IUCN Red List, 2021).
Limited research into their population trends complicates conservation efforts, highlighting the need for greater scientific focus on this species (Mongabay, 2015).
Diet
The Eastern long-beaked echidna is insectivorous, with a particular fondness for earthworms. They use their specialised snout and long, sticky tongue to extract prey from soil and rotting logs. This foraging behaviour is an essential part of their ecological role, as it contributes to soil aeration and nutrient cycling (Academic OUP, 2009).
Reproduction and Mating
As a monotreme, the Eastern long-beaked echidna lays eggs rather than giving birth to live young. Females lay a single leathery egg, which they incubate in a pouch for approximately 10 days. Once hatched, the puggle remains in the pouch for up to two months, feeding on milk secreted from specialised mammary glands (IUCN Red List, 2016).
Geographic Range
The Eastern long-beaked echidna is endemic to the montane forests of Papua New Guinea, thriving at elevations between 2,000 and 3,000 metres. Their range is limited to remote, forested highlands, with populations scattered across the island (AP Science Foundation, 2009).
FAQ
What is the Eastern long-beaked echidna?
The Eastern long-beaked echidna (Zaglossus bartoni) is one of the most unique mammals on Earth. As an egg-laying monotreme, they are part of an ancient lineage that has survived for millions of years. Endemic to Papua New Guinea, they are known for their elongated snout and nocturnal habits (Mongabay, 2015).
Why is the Eastern long-beaked echidna Vulnerable?
Their primary threats include habitat destruction from palm oil and timber deforestation and mining, as well as hunting for bushmeat. Despite legal protections, enforcement is weak, and their populations are in decline (IUCN Red List, 2016).
What does the Eastern long-beaked echidna eat?
Earthworms form the majority of their diet, along with other soil-dwelling invertebrates. They forage using their long snout and sticky tongue, an adaptation perfect for extracting prey from soil and decaying wood (Academic OUP, 2009).
How does the Eastern long-beaked echidna reproduce?
Females lay a single egg, incubating it in a pouch for about 10 days. Once the young hatches, it stays in the pouch for up to two months before becoming independent (IUCN Red List, 2016).
Where is the Eastern long-beaked echidna found?
They inhabit the remote montane forests of Papua New Guinea, at elevations between 2,000 and 3,000 metres. These habitats are increasingly threatened by human activities (AP Science Foundation, 2009).
