LISTA PRELIMINAR DE LOS MOLUSCOS DE LA CIÉNAGA GRANDE DE SANTA MARTA (COLOMBIA)

Abstract

38 mollusc species of 24 families and 30 genera, living in the Ciénaga Grande de Santa Marta or its mouth are listed. Among these 32 are marine, tolerating brackish water (marine euryhaline), 4 extremely euryhaline and 2 freshwater species (limnetic). Empty shells of some species have a much greater distribution in the Ciénaga than the actual distribution of the live species. The environmental factors of the Ciénaga are described briefly.
