The Seychelles snail, thought extinct due to climate change has been rediscovered at the UNESCO World Heritage Site of Aldabra Atoll in the Indian Ocean island nation of Seychelles. It is feeling much better thank you
The snail once thought to have been among the first species to go extinct because of climate change has reappeared in the wild (or perhaps never disappeared). The mollusk, which is endemic to the Aldabra coral atoll — a UNESCO World Heritage Site — had not been seen on the islands since 1997 approximately a year after Earth stopped warming.
“Could we live without this little snail? Almost certainly,” said Stuart Pimm, a conservation ecology professor at Duke University. “But we simply do not know what species are going to do for us in an economic sense. Probably from the time that somebody baked the first loaf of bread, a housewife said, ‘I hate bread mold and I wish it would disappear forever.’ And of course we know the scientific name of bread mold is penicillin.”
“I was so surprised; no one (on the expedition) had ever seen the snail before,” Brice said. “It’s quite amazing.”
Catherina Onezia, a senior ranger and assistant training officer for the foundation, said the team was “going crazy” with excitement over the finding.
“It shows that Aldabra has a lot of secrets still, and hopefully (we) will continue to find interesting things,” Onezia said.
Mollusk experts Vincent Florens and Pat Matyot confirmed the discovery after analyzing the discovery team’s photos. Florens, an associate professor of ecology at the University of Mauritius, told The Associated Press the Aldabra banded snail was “the only possible identification,” citing the snail’s distinctive shell pattern and locality.
(…) The snail’s apparent demise was linked to declining rainfall on Aldabra, and was widely considered to be among the first species whose extinction could be directly tied to global warming, said biologist Justin Gerlach, a scientific coordinator for the Nature Protection Trust of Seychelles.
The once-plentiful snail’s population declined exponentially between 1970 and 1990, and the last juvenile snail was found in 1976. The Seychelles Islands Foundation said the discovery of some juvenile snails is encouraging, as they are believed to be particularly vulnerable to desiccation because of reduced rainfall.
“Only time will tell if they can survive the threats of climate change and sea level rise,” Gerlach said.
