Lost Rainbow Toad Found After 87 Years

Herpetologists at Conservation International have rediscovered the exotic Sambas stream toad (aka Borneo rainbow toad, aka Ansonia latidisca) after 87 years of evasion, and released the first ever photographs of the brightly colored amphibian.

The spindly-legged species was last seen in 1924 and European explorers in Borneo only made monochrome illustrations of it. A decade or so later, the CI and the SSC Amphibian Specialist Group added the species to its World’s Top 10 Most Wanted Lost Frogs campaign.

Indraneil Das of Universiti Malaysia Sarawak decided to hunt down the lost frog, and his team looked in the nearby area of Western Sarawak. In the summer of 2010 they made evening searches along the 1,329 meter high ridges of the Gunung Penrissen range to look for the toad.

After months of fruitless hunting, Das decided to include higher elevations in the team’s search. Then, one night, graduate student Pui Yong Min found the small toad two meters up a tree. Later they found another.

In the end the team had found three individuals of the missing toad species — an adult female, an adult male and a juvenile, ranging in size from 51 mm to 30 mm. All three toads exhibited those gangly limbs and the brightly colored patterns on their backs.

Talking about his team’s discovery in a press release, Das says, “They remind us that nature still holds precious secrets that we are still uncovering, which is why targeted protection and conservation is so important.”

Robin Moore of Conservation International agrees, saying in the release, “it is good to know that nature can surprise us when we are close to giving up hope, especially amidst our planet’s escalating extinction crisis.”

The slender-legged critter is only the second species on the “World’s Top 10 Most Wanted Lost Frogs” list to be found. In September 2010, the Rio Pescado Stubfoot Toad was rediscovered in Ecuador after 15 years of hiding. The spotty frog is sadly clinging on to survival.
