Pomacea bridgesii
(Ampullariidae)
|
|
The shell of Pomacea bridgesii--one of several species called apple snail--usually has 5 to 6 whorls. The most obvious characteristic of the shell its "square shoulders" (flatness at the top of the whorls) and almost 90-degree sutures. The shell opening (aperture) is large and oval, and the umbilicus is large and deep. The size of the shell varies from 1-1/2-2 inches wide, and slightly taller than wide. The spire is high and sharp. Color is variable, from yellow, green, to brown, with or without dark spiral bands. The yellow variation is well known in the aquarium trade as the "golden mystery snail." Pomacea bridgesii is native to Amazon River system.

Catalog and bibliography of the nonindigenous nonmarine snails and slugs of the Hawaiian Islands 
"The impacts of alien species are one of the major threats faced by many ecosystems, especially those of islands (Cowie, 1992d). The Hawaiian Islands are no exception. In order to evaluate potential impacts and to develop control measures or management practices to deal with alien species, a basic understanding of their biology is necessary. A prerequisite to this is knowledge of the identities of the species that have invaded the region of concern. To address this need for the non-marine snails and slugs introduced to the Hawaiian Islands, this catalog lists all the species that have been recorded as aliens in the wild in the Hawaiian Islands (22 freshwater and 63 terrestrial species). It complements the recently published catalog of the native species (Cowie et al., 1995a). The two works together constitute a complete listing of the recorded land and freshwater snail fauna of the archipelago. Many of the species are included in a list of type material in the Museum of Comparative Zoology, Harvard University (Johnson, 1996)." [ed.: quoted from introduction of paper]
