…And New York is pretty much the only place in the world you can see them now, sadly. They’re extinct in the wild, which is unsurprising considering their native habitat is made up of just two hectares along the Kihansi Gorge in Tanzania. When a dam blocked 90% of the water flow to their waterfall habitat, the Kihansi toad population crashed. An outbreak of the amphibian dread-disease chytrid fungus cut the remaining population down to critical numbers, prompting the Wildlife Conservation Society to swoop in and rescue 499 of the tiny toads and whisk them back to the Bronx.
Although some of the toads were sent to five different zoos in the US, only the Bronx Zoo and the Toledo Zoo managed to keep them alive. As it turns out, evolving in such a specific area left the toads with very specialized needs, and the zoo has set up pure mist sprayers from filtered water, halogen lamps, and disease-free specially-bred insects for food. Now that they’re able to keep the toads alive and breed them successfully in captivity, WCS is working towards a re-introduction plan that involves an artificial mist system and the eradication of invasive plant species.
For now though, you can see them at the new World of Reptiles exhibit at the Bronx Zoo. Kihansi spray toads are unusual, charismatic amphibians — mustard yellow in color, and tiny enough to sit on the face of a dime. Unlike most amphibians, they also give birth to tiny, purple-ish live young, small enough to sit on the head of a pin.
If that’s not a poster child of cuteness for conservation, I don’t know what is.
