Kihansi Spray Toad has sexual reproduction. Captive breeding at Toledo Zoo and New York Bronx Zoo have been successful as evidenced by the following video showing reintroduction of captive bred Kihansi spray toads to their native habitat in 2012. Nectophrynoides asperginis (Kihansi Spray Toad) is a species of amphibians in the family toads. [11][14] In 2012, scientists from the center returned a test population of 48 toads to the Kihansi gorge, having found means to co-inhabit the toads with substrates presumed to contain chytrid fungus. The last confirmed record of wild Kihansi Spray Toads was in 2004. [1] In 2003 there was a final population crash in the species. They are listed as extinct in the wild by IUCN and in cites appendix i. Researchers suggest that reintroduction of the species in the wild might take time because it needs to adapt slowly to the wild habitat in which it needs to search for food, evade predators, and overcome disease, in contrast to the controlled environment they lived in during captivity.[16]. It is listed in cITES Appendix i. Habitat. Held in hermetically sealed terrariums, the colony of Kihansi spray toads is fed fruit flies bred on site and treated to 14 timed-intervals of misting through spigots of specially filtered water. The biology of this toad and its restricted range also make it especially susceptible to disturbance by humans. It has adapted to giving birth to fully formed live young to avoid having eggs washed away by the spray from the powerful waterfalls of the gorge. [10] By December 2004, fewer than 70 remained in captivity, but when their exact requirements were discovered greater survival and breeding success was achieved. Take your favorite fandoms with you and never miss a beat. Habitat: The Kihansi spray toad used to live in the Kihansi River Gorge, which is located in the Eastern Arc Mountains of Tanzania. In August 2010, a group of 100 Kihansi Spray Toads were flown from the Bronx Zoo and Toledo Zoo to their native Tanzania, as part of an effort to reintroduce the species into the wild, using a propagation center at the University of Dar es Salaam.

[2] The Kihansi spray toad is currently categorized as "Extinct in the wild" by the International Union for Conservation of Nature (IUCN), though the species persists in ex situ, captive breeding populations. The Bronx Zoo also has several thousand Kihansi spray toads, and it opened a small exhibit for some of these in February 2010. The species was listed as Extinct in the Wild in May 2009. Adults males of the species can grow be up to 0.75 inches, while females can reach 1.1 inch. In 2010 Toledo Zoo transferred 350 toads to Chattanooga Zoo, which has created a small exhibit for them. [7], Prior to its extirpation, the Kihansi spray toad was endemic only to a two-hectare (5-acre) area at the base of the Kihansi River waterfall in the Udzungwa escarpment of the Eastern Arc Mountains in Tanzania. In 2003 there was a final population crash in the species. Reproduction is dioecious. C This article has been rated as C-Class on the project's quality scale. In August 2010, a group of 100 Kihansi spray toads were flown from the Bronx Zoo and Toledo Zoo to their native Tanzania,[9] as part of an effort to reintroduce the species into the wild, using a propagation center at the University of Dar es Salaam. Recently more than 2,000 Kihansi spray toads (Nectophrynoides asperginis), an amphibian species that was declared extinct in the wild in 2009, made the long journey from Toledo, Ohio, and Bronx, New York, to Africa.They were returning to their native habitat in the Kihansi Gorge in Tanzania.
