Hyloxalus anthracinus
Hyloxalus anthracinus
Hyloxalus anthracinus is a frog in the family Dendrobatidae (order Anura), recorded as Critically Endangered and tied to Ecuador.
Appearance
The adult male frog measures 16.2–19.0 mm in snout-vent length and the adult female frog 17.1–23.6 mm. The skin of the dorsum is mottled with lighter marks. Female frogs have white bellies.
Range and habitat
Its natural habitats are páramo, very humid montane forest, and lower humid montane forest. It is also threatened by habitat loss, that scientists attribute to agriculture, development, human transportation routes, and pyroclastic events. The frog's range includes some protected parks, for example Parque Nacional Sangay, Parque Nacional Rio Negro Sopladora, Parque Nacional Cajas, and Siete Iglesias Municipal Ecological Conservation Area.
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
Chytrid fungus, collection, and wet-forest loss are the usual pressures on frogs with a high threat category.
