Figure 10. At this website, one can view lists of native freshwater snails by state or province boundary, and plot distributions of snails by political boundaries. Egg masses with large, white eggs were laid by the native Florida applesnail and should be left undisturbed, as they do not pose a threat and are the principal food of the Everglades kite. The brown garden snail or European brown snail is native to the Mediterranean and western Europe as far north as Britain. The females emerge from the water, usually at night, to lay white or bright pink egg masses on stable substrates such as tree trunks, pilings, seawalls, or even plant stems. There are four species of Pomacea in Florida, one of which is native and considered beneficial (Capinera and White 2011). I’m very fond of snails, certainly. Egg masses of introduced and native Pomacea spp. The Apple Snails all look the same and have similar dull brownish bands of color, and it takes an expert to tell them apart. The New Guinea flatworm is considered a danger to snails wherever it has been introduced and is listed in the 100 "world's worst invasive alien species", according to the International Union for the Conservation of Nature. Of the four species of applesnails in Florida, only the Florida applesnail is a native species, while the other three species are introduced. “Pomacea” means “apple”—the snails were named for their round shape and large size (some are as big as three inches in diameter). Like many exotics, Island apple snails are thought to have been brought to the United States through the tropical pet industry and released into the wild in the 1980s. Hobbyists liked them because they were very efficient at scraping algae off the glass and keeping the tanks clean. Over the next decade, government officials spent more than $1 million to eradicate them. in the continental U.S. a) Pomacea haustrum, titan applesnail; b) Pomacea diffusa, spike-topped applesnail; c) Pomacea canaliculata, channeled applesnail; d) Pomacea paludosa, Florida applesnail; e) Pomacea maculata, island applesnail. In the 1980s, pet dealers in the US began importing Apple Snails from South America for the aquarium trade. These native snails have suffered more recorded extinctions in the past 400 years due to the destruction of their natural habitats, invasive predators, and climate change. The other applesnails found in Florida seem not to be spreading or causing injury. Adult island applesnail, Pomacea maculata (Perry, 1810). The Florida apple snail is the only member of the apple snail family (Ampullariidae) that is native to th is continent (Burch 1982), but at least three other species of Pomacea have become established in Florida: P. diffusa (Thompson 1984, Rawlings et al. •Hatch approx. Egg mass of the titan applesnail, Pomacea haustrum (Reeve, 1856). Giant African snail (Achatina fulica (Bowdich, 1822)), an important invasive snail, was recently found in South Florida, USA. Despite being much smaller than the Island Apple Snail, the Florida Apple Snail, produces considerably larger eggs that are pea-sized, compared to the tomato-seed-sized eggs of the Island Apple Snail. Of the four species of applesnails in Florida, only the Florida applesnail is a native species, while the other three species are introduced. Pomacea paludosa (native Florida apple snail) is found in wetlands in the southeastern United States. It is likely the last remaining species in the Endodonta genus. Pomacea insularum is the most common of four non-native apple snails found in Florida. Daggerwing Nature Center Manager, Sean Mallee tells you how to spot the differences between the two, as well as the benefits of Native Florida Apple Snails on the Florida ecosystem! The invasive apple snail, Pomacea maculata continues to spread in freshwaters of Florida and appears to be a strong competitor of the native Florida apple snail (P. paludosa).Little is known about effects of predators on either species and we … Figure 8. It cannot survive low winter temperatures that occur in the northern tier of Florida counties and northward except where the water is artificially heated by industrial wastewater or in warm springs. The most effective management methods are hand or mechanical removal of snails and egg masses. It is marketed as an aquarium species under the name "golden applesnail." Florida Land Snail Gallery - Page Two (Click on the images for a more detailed version | additional images.) A carnivorous species (Florida rosy wolfsnail, Euglandina rosea) was later introduced by the United States government, in an attempt to control A. fulica, but the rosy wolf snail instead heavily preyed upon the native Partula snails, causing the extinction of most Partula species within a decade. Florida applesnail, Pomacea paludosa (Say, 1829). Pomacea diffusa Blume, 1957, the spike-topped applesnail, is a Brazilian species that was introduced into southern Florida, probably in the 1950s. An extensive eradication effort was initiated consisting of pesticide applications, debris removal and hand collections.
