The Boggomoss Snail is a mollusc species that can only be found in Queensland’s Dawson Valley, hence the alternate name Dawson Valley Snail. This exceptionally rare snail was first described in 1996 by the scientist John Stanisic who discovered it.

The Boggomoss is a relatively small and fragile organism with a maximum width and height of 26mm and 16mm, respectively. Its thin, semi-transparent shell is almost flat with a tiny central depression and slightly elevated spire. Adult individuals have distinct blackish stains on their shells which are actually markings on the roof of their lungs.

Flooding has a major impact on the survival of the Boggomoss Snail. It is either killed instantly or washed away from its natural range to an unsuitable habitat exposed to predators and other threats. It can also remove essential elements within its ecosystem such as dead logs, leaf litter, and other types of ground cover. The Boggomoss Snail is also vulnerable to predatory creatures such as pigs, toads, and mice. It can also easily die from trampling of grazing animals in the area.

The frequency of flooding is attributed to the land clearing efforts for man-made infrastructures and activities. And when there is a lack of trees and vegetation in the surroundings, it also increases the risk of drought and intense fires, which further alters or damages the snail’s natural habitat. As more human settlements and industrial projects are positioned within and around the snail’s natural habitat, mortality rate for this snail species becomes imminently high and guaranteed.
