Gastropod is a group of mollusca living in various habitats. They exist in marine in freshwater territory as well. The Way Kambas National Park is a protected area, yet research on freshwater gastropod has never been conducted. This research was aimed to study the existing type of gastropod based on their habitats, morphology, anatomy and distribution. The methods used in this study by taking samples randomly and three times repetitions. There have been found six types of gastropod consisting of four freshwater gastopods, i.e. Digoniostoma truncatum, Melanoides tuberculata, Indopanorbis exutus and Pomacea canaliculata; two brackish gastropods, i.e. Neritina violace, Littoraria scabra; and also three kinds of shells of marine gastropod. The highest type sum found in the Way Penet, i.e. four types, while in the Way Kambas and Kali Biru are found two brackishwater gastopods. There was no gastropod found in the Kali Binjai, Kali Batin and the Way Kanan. The Way Penet habitat tended to be freshwater territory with temperature of 30 degree C, while the Kali Biru and the Way Kambas tended to brackishwater and marine territory with temperature of 26 degree C - 30 degree C. Anatomy differences of the reproductive system stand out that Melanoides tuberculata species broods its egg in the uterus, and bears 20-90 young small snails.
