Griffiths O, Cook A, Wells SM, 1993. Since 1955 snails of the Euglandina rosea species complex and Platydemus manokwari flatworms were widely introduced in attempted biological control of giant African snails (Lissachatina fulica) but have been implicated in the mass extinction of Pacific island snails. Increasing trade between countries could also lead to the introduction of E. rosea into new habitats (Cowie, 1998). members of this invasive species. Surviving populations (the date of introduction is given in parentheses) can be found in Bermuda (introduced 1958-60), Grand Comorro (1970), Guam (1958), Hawaii (1955), Madagascar (1970), Mauritius (1959), Micronesia (? The extinction of Partula on Moorea. Methods ... been successfully deployed in the detection of two pl ant species. Chemical components of the mucus and perhaps the shell, together with the physical dimensions of the shell are the most important determinants of prey suitability (Cook, 1989a, b).

CABI Compendium: Status inferred from regional distribution. Land Mollusca of North America (North of Mexico). The purposeful introduction of the land snail Euglandina rosea, which feeds exclu- sively on snails and slugs, has been implicated as a major factor in the decline of diverse Pacific island land snail faunas. Predation by the introduced carniverous snail Euglandina rosea (Ferussac) on endemic aquatic lymnaeid snail in Hawaii. The distribution in this summary table is based on all the information available. Invasive species may negatively impact native species in any number of ways including: eating them, competing with them, mating with them and decreasing genetic diversity, introducing pathogens and parasites that sicken or kill them, and disrupting available nutrients. The IUCN ISSG has listed E. rosea amongst 100 of the world's worst invasive species and condemned its use as a biological control agent. E. rosea has had a negative impact on native snail species in the countries into which it has been introduced. These hatch after 30 to 40 days. Euglandina rosea (nomeada rosy glandina [3], rosy wolfsnail ou cannibal snail [4] [5], em inglês) é uma espécie de molusco gastrópode terrestre predador pertencente à família Spiraxidae e classificada por Férussac no ano de 1821. Individuals live up to 24 months and adults lay 25 to 35 eggs in a shallow pocket in the soil. Auffenberg K, Stange LA, 1986. This means that even though each individual snail is both male and female they require a “partner” for fertilization. Rosy wolfsnail can lay approximately 25 - 40 eggs a year.

The eggs hatch after 30 days and the individuals that emerge can live up to 2 years. There are examples of invasive species altering the evolutionary pathway of native species by competitive exclusion, niche displacement, hybridization, introgression, predation, and ultimately extinction. A considerable international effort is underway to conserve these threatened island snails, which includes captive breeding programmes and the creation of reserves free from Euglandina. Observations on the biology of the carnivorous snail Euglandina rosea Ferussac. Oryx, 37(1):91-96. According to the International Union for the Conservation of Nature (IUCN), native partulid species began disappearing from Raiatea rapidly after the introduction of the carnivorous snail Euglandina rosea in the late 1980s, “By 1992 there were few left and no live wild individuals of this species were found during surveys in 1994 and 2000.

Land Mollusca of North America (North of Mexico). Detailed coverage of invasive species threatening livelihoods and the environment worldwide. The Global Invasive Species Database was developed and is managed by the Invasive Species Specialist Group (ISSG) of the Species Survival Commission (SSC) of the International Union for Conservation of Nature (IUCN).It was developed as part of the global initiative on invasive species led by the erstwhile Global Invasive Species Programme (GISP) in 2000. In: Endangered and Threatened Wildlife and Plants; Determination of Endangered Status for 38 Species on Molokai, Lanai, and Maui; Final Rule. Instead, E. rosea invaded native forests and is believed to have rendered several endemic species of snails extinct (Howarth 1991). Pilsbry HA, 1946. Journal of Conchology, Supplement 2:89:96.

These predatory snails were originally introduced to Hawaii in an attempt to eliminate another invasive species, the giant African land snail, Achatina fulica. The organisation of feeding in the carniverous snail Euglandina rosea Férussac. Euglandina appears to detect its prey by following slime trails (Cook, 1985b; Clifford et al., 2003), which it does more than 80% of the time (Clifford et al., 2003) or by detecting dissolved substances in water (Kinzie, 1992).
