Freshwater Neritidae in Southeast Sulawesi, Indonesia

The present research was conducted from March 2019 to August 2020 in the natural and artificial inland waters of Southeast Sulawesi Province. The purpose of this research was to determine the species diversity of the freshwater Neritidae family in Southeast Sulawesi. It is expected that this research will reveal the biodiversity potential of freshwater Neritidae snails as a form of exploration in optimizing the utilization of the Neritidae commodity in Southeast Sulawesi. Determination of the locations for the Neritidae sampling was done through the purposive sampling method and the sampling of the biota used the simple random sampling method at locations that had been predetermined based on the distinctive habitat characteristics of rocky rivers and fast currents. Neritidae samples were collected manually with gloves. As Neritidae live attached to rocks and other hard objects in the river, their collection was relatively easy. Neritidae snails in the fresh waters of Southeast Sulawesi consist of 22 species from 4 genera which are generally distributed in river waters with currents and rocky substrates. The types of Neritidae snails found in Southeast Sulawesi include: Clithon castaneus, Clithon corona, Clithon diadema, Clithon dominguense, Clithon faba, Clithon flavovirens, Clithon fuliginosum, Clithon oualaniense, Clithon sowerbianus, Neritina canalis, Neritina cornuta, Neritina knorri, Neritina labiosa, Neritina petiti, Neritina pulligera, Neritina punctulata, Septaria borbonica, Septaria luzonica, Septaria porcellana, Vittina coromandeliana, Vittina pouchetii, and Vittina variegata. Southeast Sulawesi Neritidae snails have very large and diverse polymorphism, making the Neritidae family to be one of the largest snail communities that make up the freshwater ecosystem.
