Found in Indonesia. Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Dwarf Salamander

<em>Bolitoglossa rufescens</em>, the common dwarf salamander, is a plethodontid salamander native to Mexico and classified as Least Concern by the IUCN Red List. The species typically inhabits freshwater environments, moist forests, and wetlands across its range in Mesoamerica, where it is associated with humid lowland and montane forest habitats characterized by abundant leaf litter, mosses, and epiphytic vegetation. As a member of the genus <em>Bolitoglossa</em>, this salamander belongs to the largest genus of salamanders in the world, with members distributed throughout Central and South America. <em>Bolitoglossa rufescens</em> is lungless, relying entirely on cutaneous and buccal respiration, which makes it highly dependent on moist microhabitats to maintain adequate gas exchange through its skin. The species is typically arboreal or semi-arboreal, foraging among bromeliads, mosses, and leaf axils for small invertebrates including mites, springtails, and other arthropods. Its direct-developing eggs bypass a free-swimming larval stage, an adaptation that allows populations to persist in habitats without standing water. Habitat degradation through deforestation and agricultural expansion poses a concern for local populations. Biological traits of this species remain poorly documented in the scientific literature.

Komodo Dragon

The Komodo dragon is the largest living lizard. It is found only on a few Indonesian islands.
