鈥淎mphibian declines are seen as an indicator of the onset of a sixth mass extinction of life on earth,鈥 reads the first line in a recently published in Nature Communications鈥攍ucky then, that this same paper goes on to describe the rediscovery of a frog that was presumed extinct.
The , which bears bright white spots decorating its belly and throat, was discovered sometime in the 1940s, but 1955 was the last time that anybody caught a glimpse of it, just after the frog鈥檚 wetland habitat in Israel's was drained. Decades later after many a fruitless search, the amphibian became the first on the globe to be labeled extinct, in 1996.
Now that status is being reversed, as researchers publish their paper showing that since 2011, when a park ranger in the Hula Valley named Yoram Malka stumbled across the first one, researchers have found 14 Hula painted frogs.
鈥淪cientists tend to err on the side of caution before declaring something extinct, so we were pretty sure this frog was gone,鈥 said , from the , to .
With their renewed faith, the researchers estimate that there may be between 100 and 200 of the frogs alive and well in the valley today. The way to buoy that population is to take steps to protect the frogs so that they don鈥檛 once again disappear from view, the study authors say. Efforts also need to be made to figure out more about the frog. 鈥淲e know nothing about its life history鈥e don't know if it鈥檚 active at night. We don't know when it breeds, or how it breeds, or what its tadpoles look like,鈥 said lead study author to National Geographic. Answering those questions appears to be the next step. 鈥淚 hope it will be a conservation success story,鈥 Gafny said to . 鈥淲e don鈥檛 know anything about their natural history and we have to study them. The more we know, the more we can protect them.鈥
What makes the discovery even more impressive is that the frogs are the only survivors of their genus Latonia, meaning that they have no living relations. Previously, scientists had believed that the last remnants of that genus died out 10,000 years ago, but this discovery shows that up to be untrue.
As it exists now, the Hula painted frog has also remained relatively unchanged across the millennia鈥攖urning it into something known colloquially as a 鈥榣iving fossil鈥. It鈥檚 a rare trait, and one that belongs to only a few other animals on the planet, like the for instance, National Geographic reports.
Together with the tangible threats to their habitat, all of the above makes Hula painted frogs seem delicate, untouchable鈥攑erhaps even doomed. But Moore said, 鈥淚t鈥檚 a dangerous message to send that we鈥檙e too late to do anything to save these species鈥ecause then people won鈥檛 do anything.鈥 Rather, people feel should feel optimistic about the fact that the frog has survived this long. 鈥淚t鈥檚 a real testament to the resilience of nature if given the chance,鈥 said Moore.
