Critically Endangered
Hyperolius tanneri
Hyperolius tanneri
Hyperolius tanneri is a reed frog in the family Hyperoliidae (order Anura), recorded as Critically Endangered and tied to Tanzania.
Appearance
Males measure 20–23 mm (0.79–0.91 in) and females 29–34 mm (1.1–1.3 in) in snout–vent length. The dorsum is green and has light canthal and dorsolateral stripes. The fingers and toes are yellow, and the throat and ventrum are blue-green.
Range and habitat
It is endemic to the West Usambara Mountains in northeastern Tanzania.
It is only known from two sites, one near the Mazumbai Forest Reserve at 1,410 m (4,630 ft) above sea level, and the other one in the Shume-Magambo Forest Reserve at 1,920 m (6,300 ft) asl.
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
Because the species is only known from two sites in one location suffering from habitat loss, it has been assessed as "Critically Endangered" by the International Union for Conservation of Nature (IUCN).
Chytrid fungus, collection, and wet-forest loss are the usual pressures on frogs with a high threat category.
Hyperolius tanneri is Critically Endangered on this catalog because that is the IUCN category stored on Wikidata. Confirm the official criteria and any later count on iucnredlist.org.
