Pomacea canaliculata, commonly known as the golden apple snail or the channeled apple snail, is a species of large freshwater snail with gills and an operculum, an aquatic gastropod mollusc in the family Ampullariidae, the apple snails.
Perivitellin-2 (PV2) is a pore-forming toxin present in the egg perivitelline fluid of the apple snails Pomacea maculata (PmPV2) and Pomacea canaliculata (PcPV2). This protein, called perivitellin, is massively accumulated in the eggs (~20 % total protein). As a toxin PV2 protects eggs from predators, but it also nourishes the developing snail ...
Pomacea canaliculata egg clusters. Several apple snail genera (Pomacea, Pila and Asolene/Pomella) deposit eggs above the waterline in calcareous clutches that can be recognized by their light pink color. [13] This remarkable strategy of aquatic snails protects the eggs against predation by fish and other aquatic inhabitants.
Pomacea maculata is a species of large freshwater snail with an operculum, an aquatic gastropod mollusk in the family Ampullariidae, the apple snails. The common name of its synonymous name Pomacea insularum is the island apple snail. Together with Pomacea canaliculata it is the most invasive species of the family Ampullariidae. [2]
Ovorubin (PcOvo or PcPV1) is the most abundant perivitellin (>60 % total protein) of the perivitelline fluid from Pomacea canaliculata snail eggs. This glyco-lipo-caroteno protein complex is a approx. 300 kDa multimer of a combination of multiple copies of six different ~30 kDa subunits.
Pomacea is a genus of freshwater snails with gills and an operculum, aquatic gastropod mollusks in the family Ampullariidae, the apple snails. The genus is native to the Americas ; most species in this genus are restricted to South America.
