Lissachatina fulica
Summary
Lissachatina fulica is a species of large land snail that belongs in the subfamily Achatininae of the family Achatinidae. It is also known as the Giant African land snail. It shares the common name "giant African snail" with other species of snails such as Achatina achatina and Archachatina marginata. This snail species has been considered a significant cause of pest issues around the world. Internationally, it is the most frequently occurring invasive species of snail.
Outside of its native range, this snail thrives in many types of habitat in areas with mild climates. It feeds voraciously and is a vector for plant pathogens, causing severe damage to agricultural crops and native plants. It competes with native snail taxa, is a nuisance pest of urban areas, and spreads human disease. This snail is listed as one of the top 100 invasive species in the world.
Subspecies within this species:
Lissachatina fulica castanea (Lamarck, 1822)
Lissachatina fulica coloba (Pilsbry, 1904)
Lissachatina fulica hamillei Petit, 1859
L. f. rodatzi Dunker, 1852
L. f. umbilicata Nevill, 1879
The species is native to East Africa, but it has been widely introduced to other parts of the world through the pet trade, as a food resource, and by accidental introduction.
This species has been found in China since 1931 and its initial point of distribution in China was Xiamen. The snail has also been established on Pratas Island, of Taiwan, throughout India, the Pacific, Indian Ocean islands, Southeast Asia and the West Indies. The species was established in the United States in 1936. They were brought to the U.S. through imports, intended for educational uses and to be pets. Some were also introduced because they were accidentally shipped with other cargo. An eradication effort in Florida began in 2011 when first sighted, and the last sighting was in 2017. In October 2021 the Florida Department of Agriculture declared the eradication a success after no further sightings in those four years. In June 2022 the snail was again found in Florida.
