Colonia Robber Frog

<em>Eleutherodactylus audanti</em>, the Colonia robber frog, is a direct-developing frog in the family Eleutherodactylidae assessed as Vulnerable by the IUCN. Members of the genus <em>Eleutherodactylus</em> are notable for their direct development, bypassing the free-living tadpole stage entirely and hatching as miniature froglets from terrestrial eggs, a reproductive strategy that reduces dependence on standing water for breeding. This species inhabits freshwater-associated environments, moist tropical forests, and wetland margins, occupying humid microhabitats within the leaf litter and understorey vegetation. The Vulnerable assessment reflects population declines associated with habitat loss, chytrid fungal disease, and potentially climate-driven changes in forest moisture regimes. Robber frogs in this genus feed opportunistically on small invertebrates encountered in their forest floor microhabitat. <em>Eleutherodactylus audanti</em> has not been confirmed from any specific country according to current records, suggesting either a highly restricted or poorly documented distribution. Conservation of moist forest habitats is considered essential to the long-term survival of this species. Biological traits of this species remain poorly documented in the scientific literature.
