Chucanti Salamander

The Chucantí Salamander (Bolitoglossa chucantiensis) is a Critically Endangered plethodontid salamander known from the Chucantí mountain massif in the Darien region of eastern Panama. The genus Bolitoglossa represents the largest genus of salamanders globally, with the greatest diversity in Central and South America. B. chucantiensis was described from a small area of cloud forest at mid-to-high elevations in the Serranía de Majé range, an isolated and poorly surveyed mountain system in the Darién Province. Its Critically Endangered status reflects an extremely restricted range (estimated area of occupancy potentially under 10 km²), ongoing deforestation threatening its cloud forest habitat from agricultural expansion and cattle ranching, and the threat of chytridiomycosis, the amphibian fungal disease that has devastated salamander and frog populations across the Americas. Like other Bolitoglossa species, it is a direct-developing salamander that bypasses a free-swimming larval stage, laying eggs in moist terrestrial habitats. Conservation of the Chucantí Nature Reserve, established partly to protect the biodiversity of this mountain, is critical for the survival of this species.

Koala

Iconic marsupial of eastern and southeastern Australia, koalas weigh up to 15 kg and spend up to 22 hours daily sleeping to conserve energy from their low-calorie eucalyptus leaf diet. Highly specialized to process toxic eucalyptus compounds that would kill most other mammals, they have gut microbiomes uniquely adapted for detoxification. Listed as Endangered in 2022, with populations decimated by chlamydia disease, habitat clearing, and climate change.
