This is the other animal I went to the Bronx zoo to see. This is the Kihansi spray toad, native to a an area at the base of the Kihansi River waterfall in Tanzania. Their entire habitat was less than 0.0077 square miles.
In 1999, Tanzania built a dam across the Kihansi, which reduced the amount of water going through the waterfall, which reduced the overall amount of spray that created a moist enough environment for them. A sprinkler system was added to help keep them alive, but in 2003, the system broke at the same time that the chytrid fungus showed up in that area and the dam was flushed, which released pesticides into their environment. In 2004, they became extinct in the wild. We are fortunate that they breed well in captivity.
Today, the Bronx zoo is one of the only places on the planet where you can see them. The others are: the Toledo Zoo, the Chattanooga Zoo, the Detroit Zoo and the Henry Doorly Zoo in Omaha.
