Abstract

Golden apple snail (Pomacea canaliculata) has wide adaptability and rice fields are ones of the habitats for the snail. Golden apple snail has phenotypic variations. This study conducted to determine the morphology of golden apple snail from several rice fields in Bali, Indonesia. Samples were taken at twelve locations in three districts. Three rice fields were taken in each location. Samples were taken in quadrate plot of 1x1m at four points each rice field. The morphological of the golden apple snail samples were observed. The results showed that the golden apple snail shells found in all locations has a variety of colors. The color was yellowish to dark brown. The shell also has a shell band and the shell band vary in their appearance. The color of the shell band was more visible on the darker shell.
