Seven years after being declared extinct, wiped out as a result of shifting weather patterns associated with climate change, a species of snail native to the Seychelles has been rediscovered, alive and well.
Aldabra banded snails aren't widely known outside the one atoll where they're found in the West Indian Ocean, but their widely-reported demise in 2007 made them a poster child for a new era of extinction among biologists. In the 1990s, the once-plentiful snails seemed to have disappeared entirely, apparently unable to cope with the longer, drier summers associated with global warming.
Researchers who predicted climate change would lead to extinctions pointed to Aldabra banded snails as one of the first to be claimed.
But a recent discovery is now offering a glimmer of hope for the species. Late last month, a boat skipper named Shane Brice was traversing a remote part of the Aldabra atoll and spotted a "mysterious snail" he says he'd never seen before. He alerted ranger Catherina Onezia, from the Seychelles Islands Foundation (SIF).
