Common Neacomys

<em>Neacomys spinosus</em>, the common neacomys or spiny neacomys, is a small rodent in the family Cricetidae found in South America. This ground-dwelling mouse is characterized by its distinctively spiny fur, an adaptation that may provide protection against predators. <em>Neacomys spinosus</em> typically inhabits tropical lowland and montane forests, forest edges, and adjacent scrubby vegetation in northwestern South America, with its geographic range including Colombia and surrounding countries. The species forages on the forest floor and in low vegetation, and is believed to consume seeds, plant material, and invertebrates, although specific dietary data are limited. It is currently assessed as Least Concern by the IUCN, with populations considered stable across its range, though ongoing deforestation in the Amazonian and Andean foothills may present long-term threats. Biological traits such as lifespan, body size, and diet remain poorly documented for this species across its full range. <em>Neacomys spinosus</em> plays a role in seed dispersal and forms part of the prey base for small mammalian and avian predators in its tropical forest ecosystems.
