This week we published a new audio documentary that tells the story of the ongoing decline and extinction of Hawai’i’s incredible land snails. The piece explores the diverse ways in which these often overlooked creatures matter for local people and their environments.
The full audio piece is available here.
The Hawaiian Islands were once home to an incredible diversity of terrestrial snails, one of the most diverse assemblages to be found anywhere on earth. Today, the majority of these species are gone and most of those that remain are threatened with extinction. This audio piece tells the story of this ongoing decline and local efforts to prevent it, including the creation of captive populations of snails in the laboratory and behind an elaborate predator-proof fence in the forest. It weaves together the insights of conservationists, Native Hawaiian cultural practitioners, museum curators, and others to convey the significance of these often-disregarded creatures. One key aspect of this significance lies in the cultural associations of snails for Hawaiians, associations which are tied strongly to the traditional understanding that these animals sing in the forest at night. According to most biologists, however, snails have no vocal cords and cannot sing – at least not in the conventional sense of this term. This piece explores this perplexing situation, ultimately concluding that like so much else about these remarkable, disappearing, creatures, their singing must remain something of a mystery.
