Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (5 countries), and South America (Colombia, Ecuador, Venezuela). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Dwarf Salamander

Habitat

Typically found in freshwater habitats, moist forests, and wetlands.

Range

Found in Mexico.

Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.

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.
