Cloud forest rocket frog

Cloud forest rocket frogs are small poison frogs in the genus Hyloxalus (family Dendrobatidae) native to cloud forests of the northern and central Andes in Colombia, Ecuador, and Peru. Unlike the brilliantly colored poison dart frogs of lowland forests, Hyloxalus species typically display more cryptic coloration in brown, black, and olive tones with subtle dorsolateral stripes, though their skin secretions contain bioactive alkaloids providing chemical defense. They inhabit the humid leaf litter and rocky streamsides of cloud forest floors at elevations typically between 1,000 and 3,000 meters, where high rainfall and persistent mist maintain the moist conditions required for their moisture-sensitive skin and terrestrial reproductive strategies. Males carry tadpoles on their backs to small streams or seeps for development. Cloud forest rocket frogs are among the most chytrid-affected vertebrate groups globally: Batrachochytrium dendrobatidis chytridiomycosis has caused catastrophic population collapses, and several Hyloxalus species are now Critically Endangered or extinct in the wild due to this fungal disease interacting with climate change and habitat loss.
