Habitat & Geographic Range

Cloud Forest Treefrog

Habitat

Found across multiple habitat types including tropical and subtropical coniferous forests, tropical and subtropical grasslands and savannas, and Mediterranean forests and woodlands, among 6 distinct biome types spanning the Nearctic and Neotropic realms. Populations are also found in montane and highland environments at higher elevations.

Range

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

Clymene Dolphin

Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

Range

Distributed across Norway and Venezuela.

Cloud Forest Treefrog

Cloud forest treefrogs in the genus Megastomatohyla (family Hylidae) are medium to large arboreal frogs native to the montane cloud forests of Mexico and Guatemala, inhabiting humid highland forests at elevations between 1,500 and 2,800 meters. These treefrogs have large adhesive toe pads, long limbs adapted for climbing, and typically green or brown coloration with cryptic patterns matching lichen-covered bark and leaves. They breed in temporary and permanent pools in forest clearings and at stream margins, with males calling from vegetation over water on rainy nights. Larvae develop in small forest pools. The genus Megastomatohyla was separated from the large genus Hyla based on molecular and morphological studies distinguishing Middle American cloud forest specialists from their lowland relatives. Several species in this genus have experienced significant population declines attributed to chytridiomycosis in combination with habitat loss, and some are now considered Critically Endangered or Endangered. The montane cloud forests of Mexico and Guatemala harbor exceptional amphibian diversity but face deforestation pressures from agricultural expansion, charcoal production, and illegal logging that continue to reduce amphibian habitat area.

Clymene Dolphin

The Clymene dolphin, Stenella clymene, is a small cetacean endemic to the tropical and subtropical waters of the Atlantic Ocean, ranging from the Gulf of Mexico and Caribbean Sea south along both the western and eastern Atlantic margins to approximately 20 degrees south latitude. Often called the short-snouted spinner dolphin, it is the only known naturally occurring cetacean hybrid species, believed to have originated through hybridization between the spinner dolphin (S. longirostris) and the striped dolphin (S. coeruleoalba). Clymene dolphins are acrobatic and frequently perform spinning leaps similar to but less elaborate than their spinner relatives. They travel in schools typically ranging from 10 to several hundred individuals, sometimes associating with other dolphin species. The species inhabits deep offshore pelagic waters and is rarely observed close to coastlines. It feeds primarily on fish and cephalopods, foraging at night when mesopelagic prey move into shallower waters. Clymene dolphins measure approximately 1.7–2 meters in length and display a distinctive tripartite pattern of dark cape, lighter grey flanks, and white or pale yellow belly. The species is assessed as Least Concern by the IUCN due to its relatively wide range and no evidence of major population-level threats.
