Knowra Lissachatina fulica Lissachatina fulica Lissachatina fulica, the giant African land snail, is a large pulmonate land snail native to East Africa. It has become invasive across tropical and subtropical regions, where it can damage crops and ecosystems.
Pulmonata : A group of gastropod molluscs that breathe air using a lung-like mantle cavity. Its air-breathing anatomy lets it live on land without gills.
Invasive species : A non-native organism that spreads and causes ecological, economic, or other harm. Its spread beyond its native range has made it a prominent invasive species.
Agricultural pest : An organism that harms crops or livestock and reduces agricultural production. Feeding on seedlings and crops can cause substantial local agricultural losses.
East Africa : The eastern region of Africa, including countries such as Kenya and Tanzania. This region is the snail’s native range.
Lissachatina reticulata : A large African land snail species with a reticulated shell pattern. It is a close relative that can be confused with the giant African land snail.
Gastropod shell : A hard external structure secreted by many gastropods, providing protection and support. The snail’s large, conical shell protects its body and records growth.
Biological control : The use of living organisms to reduce populations of pests or other unwanted species. Control efforts must avoid introducing predators or parasites that harm native wildlife.
Biodiversity loss : A decline in the variety of genes, species, or ecosystems in a region or worldwide. Dense populations can compete with native snails and alter plant communities.
Indian Ocean : The ocean bounded by Africa, Asia, Australia, and the Southern Ocean. Island and coastal populations spread across this ocean through human activity.
Archachatina marginata : A large West African land snail species with a broad, rounded shell. Its different genus and shell shape help distinguish another African giant snail.
