Researchers rediscovered two marsupials, Ring‑tailed Glider and Pygmy Long‑fingered Possum, in forests of New Guinea, previously thought extinct for nearly 6,000 years.

About Ring-tailed Glider (Tous ayamaruensis)
- The Ring‑tailed Glider is a rare tree-dwelling marsupial related to gliding possums and known earlier only from fossil evidence discovered in Australia.
Habitat: The species survives in dense tropical rainforests of the Vogelkop Peninsula in Papua, where thick forest canopies support arboreal wildlife.
- Features:
- They are nocturnal species that eat leaves and uses its claws to extract tree sap that is left to congeal before being eaten.
- It possesses a gripping ring-like tail for holding branches, gliding ability for moving between trees, and distinctive hairless ears that give it a unique appearance.
- Concerns: Habitat threats from logging and land-clearing in New Guinea pose conservation challenges, though protection by indigenous communities has likely aided its survival.
Pygmy Long-fingered Possum (Dactylonax kambuayai)

- The Pygmy Long‑fingered Possum is a tiny marsupial species previously believed extinct and recently confirmed alive in remote forests.
- Habitat: It inhabits moist tropical forests of New Guinea, particularly old-growth tree areas rich in insects and decaying wood.
- Features and Diet:
- They are nocturnal species.
- It is a palm-sized possum that has a distinctive elongated finger used to extract insect larvae from rotting wood, while sensitive hearing helps locate prey inside trees.
- Concerns: Its extremely small population, habitat disturbance, and risk of illegal wildlife trade require careful protection and restricted disclosure of its precise habitat.
About Marsupials
- Marsupials are mammals whose young develop in a pouch, including species like the Kangaroo, Koala, Possum, and Tasmanian Devil.
- Distinct Features: Marsupials give birth to underdeveloped young that continue growing in a pouch, and many species possess strong hind limbs or specialized claws for climbing or jumping.
- Habitat: They mainly inhabit forests, grasslands, and shrublands with moderate to tropical climates where vegetation provides food, shelter, and breeding sites.
- Distribution:
- Most marsupials are found in Australia, New Guinea, and nearby islands, with a smaller number occurring in the Americas.
- There are no wild, extant (living) marsupials native to the Indian ecosystem.
- Fossil records indicate that early, ancestral marsupials existed in India around 52 million years ago following the India-Asia collision.
