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.

common grey sea slug

<em>Aeolidia papillosa</em>, commonly known as the common grey sea slug, is a nudibranch mollusc belonging to the genus Aeolidia within the family Aeolidiidae. Despite the species name referencing terrestrial and aquatic habitats including forests and freshwater, <em>Aeolidia papillosa</em> is primarily a marine organism. Its range includes Belgium, Chile, Denmark, Norway, and Sweden, indicating a distribution across the North Atlantic and into South American waters. Common grey sea slug is assessed as Least Concern on the IUCN Red List. The species is typically found in intertidal and subtidal zones, where it preys on sea anemones and stores stinging cells from its prey in its dorsal cerata for defense. Biological traits of this species remain poorly documented in the scientific literature.
