Colombian Stubfoot Toad

<em>Atelopus minutulus</em>, the Colombian stubfoot toad, is a critically endangered harlequin toad in the family Bufonidae, endemic to Colombia. This species is assessed as Critically Endangered by the IUCN, placing it among the most threatened amphibians in the world. Like many members of the genus <em>Atelopus</em>, it has suffered severe population declines attributed primarily to the lethal chytrid fungus <em>Batrachochytrium dendrobatidis</em>, compounded by habitat destruction and climate change. The species occupies tropical and subtropical moist broadleaf forests, dry broadleaf forests, and grassland and savanna habitats, suggesting broader ecological tolerance than many congeners. Stubfoot toads are characteristically diurnal and are often associated with stream margins in humid forest environments, where males typically call from rocks or vegetation near fast-flowing water. Their bright colouration in some <em>Atelopus</em> species signals toxicity, though the extent of toxicity in <em>A. minutulus</em> is not well established. Conservation efforts for Colombian stubfoot toads include captive breeding programmes and disease-resistance research. Biological traits of this species remain poorly documented in the scientific literature.
