Achatina fulica does not have hearing as a sense, so it relies on its other senses to perceive the environment. The snail can be found in agricultural areas, coastal areas, wetlands, disturbed areas, forests, urban areas, and riparian zones. They are considered an agricultural pest, costing farmers not only their crops but also economic costs. Snails in the genus Achatina (e.g., Achatina fulica, the Giant African Snail), are specifically prohibited for both interstate movement and importation into the U.S. March 07, 2014 This species is also a cheap alternative in some regions as a source of fish feed in fish farming, as they breed quickly and in large amounts.

Global Invasive Species Database. Biological Invasions 9(6):693-702. Data Description Introduction. Giant African land snails (GALS) could be devastating to Florida agriculture and natural areas because they cause extensive damage to tropical and subtropical environments. Immature, small snails that are still growing produce only spermatozoa, while larger, mature adults produce both spermatozoa and ova. Movement is an important aspect of their lives as it is necessary for mating, finding food, and escaping threats. This often leads to it being mistaken for less widespread species. Predators of Achatina fulica includes many species of rodents, wild boars, terrestrial crustaceans, and other species of snails. There is not much difference between the lifespans in the wild and in captivity. The shell is generally reddish-brown in colour with weak yellowish vertical markings but colouration varies with environmental conditions and diet. Lissachatina fulica.
