Members of the genus Ebala are small (<4mm) gastropods, the shells of which have a sinistralprotoconch. The shell is transparent, sometimes with opaque spots. In contrast to most of the families in the parent superfamily Pyramidelloidea, they do possess a radula. They are found in tropical to temperate waters, often associated with sea grass beds (e.g. Posidonia and Zostera).[citation needed]
