January 10, according to foreign media reports, the Department of Land and Natural Resources of the State of Hawaii issued a message that the last known Hawaiian golden worm (Achatinella apexfulva) died in Hawaii.

      The snail named George died on January 1 and was "14 years old." It is reported that the Hawaiian golden-topped tree snail is a terrestrial snail originally distributed on Oahu Island, and their shells have been used to make necklaces.

      The news pointed out that in 1997, the last 10 tree cogs on the earth were sent to the University of Hawaii laboratory for artificial breeding. Although the experts succeeded in cultivating newborn snails, all snails died in addition to George.

      It is worth noting that other terrestrial snails on the island of Hawaii are also threatened, with the main dangers being climate change and large-scale invasion of alien species.

      However, in 2017, researchers used a sterile razor blade to collect a portion of George's tissue and placed it in a medium that kept it active and sent it to the San Diego Zoo. Although humans have not yet cloned snails, they may be able to do it one day.
