Edgbastonia colmani

Unknown

Overview

Edgbastonia colmani is a species of small freshwater snail, an aquatic gastropod mollusc in the family Tateidae.

Jardinella colmani faces severe threats from groundwater extraction and agricultural development in its limited range around artesian springs in Queensland's Great Artesian Basin. The species' dependence on specific hydrogeological conditions makes it extremely vulnerable to water table changes and spring flow alterations. Introduced species and habitat modification from cattle grazing further compound pressures on this endemic freshwater gastropod.
