Atelopus certus
Atelopus certus, the Darien stubfoot toad or Toad Mountain harlequin frog, is a toad in the family Bufonidae endemic to Panama.
The toad
Atelopus certus is a toad in the family Bufonidae (order Anura).
Range and habitat
The toad is endemic to the Darien region of eastern Panama, and its type locality is Cerro Sapo (literally "toad mountain"), giving it its common names Refrigerator and xylophone. Its natural habitats are tropical montane and submontane forests. It breeds in forest streams where the tadpoles also develop.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Breeding
Calling males and egg sites define most frog field work. A species known from one ridge is as narrow as it sounds.
Eggs and damp skin make amphibians quick to vanish from a drained wetland or a forest stripped of litter.
In crisis
The species is threatened primarily by the advancing wave of chytridiomycosis moving through Central America, and secondarily by habitat loss, although much of its range falls within the Darién National Park, a protected area and world heritage site. Because so many other Atelopus species are in steep declines, this amphibian is seen as a priority species for ex situ conservation. In June 2010, a team of conservation partners working under the Panama Amphibian Rescue and Conservation Project mounted an expedition to the Darien and brought back a founding population of these frogs to begin an ex situ conservation program at Summit Municipal Park near Panama City.
Chytrid fungus, collection, and wet-forest loss are the usual pressures on frogs with a high threat category.
