Palmenroller

<em>Paradoxurus hermaphroditus</em> is a medium-sized viverrid mammal in the family Viverridae, distributed across South and Southeast Asia. The species inhabits a broad range of ecosystems, including tropical and subtropical forests, plantations, agricultural edges, and urban environments. It is primarily nocturnal and arboreal, foraging in tree canopies as well as on the ground. As an opportunistic omnivore, it typically consumes fruits, berries, small vertebrates, invertebrates, and occasionally birds' eggs, playing a role in seed dispersal for a variety of fruiting plant species. The common palm civet is famously associated with the production of kopi luwak, a specialty coffee made from beans that have passed through its digestive tract, raising ethical concerns about the captive keeping of wild civets for this industry. The IUCN currently assesses this species as Least Concern given its wide distribution and tolerance of modified habitats. No country-level distribution records are present in current datasets, though the species is broadly distributed across the Indo-Malayan realm. Biological traits including precise lifespan estimates, body measurements, and standardized dietary data remain poorly documented in comprehensive databases. Conservation pressures include hunting and the exotic pet trade.
