Kihansi spray toad
Nectophrynoides asperginis
The Kihansi spray toad is a tiny Tanzanian amphibian that lived only in the mist of a single waterfall gorge until a dam altered its habitat. Declared extinct in the wild, it survives in captive 'ark' colonies and has been the subject of reintroduction trials.

Quick facts
| Size | Tiny toad ~2 cm, yellowish, with live-bearing reproduction. |
| Lifespan | 5–10 years |
| Native region | Kihansi Gorge, Tanzania |
| Climate | 🌴 Tropical |
| Genus | Nectophrynoides |
Habitat & enclosure
Endemic to the spray zone of the Kihansi Falls, a wetland microhabitat sustained by waterfall mist. Construction of a hydroelectric dam cut the water flow, and chytrid disease compounded the loss, driving it to extinction in the wild. Zoo assurance colonies, supported by artificial misting systems at the gorge, anchor its survival. This profile is conservation/education only.
Diet
An insectivore feeding on tiny invertebrates in its misty habitat. Captive colonies require precise humidity and temperature control to mimic the spray zone.
Behavior & temperament
Unusually for a toad, it bears live young rather than laying eggs in water, an adaptation to its spray-zone life. It is a stark example of how a single engineering project can eliminate a species confined to a microhabitat.
