are giant african snails competitive or dependent
Achatina fulica is a species of land snail in the family Achatinidae, known commonly as the giant African snail or giant African land snail.Outside of its native range this snail thrives in many types of habitat in areas with mild climates.he shell has a conical shape, being about twice as high as it is broad. Either clockwise (dextral) or counter-clockwise (sinistral) directions can be observed in the coiling of the shell, although the right-handed (dextral) cone is the more common. Shell colouration is highly variable, and dependent on diet. Physical Description. The giant African snail can be distinguished from other snails due to their large size; when mature, the snail can reach up to eight inches (30 centimeters) in length with a diameter of four inches (10 centimeters).The snail can reach up to thirty-two grams in weight.he number of eggs that an individual snail lays often depends on the maturity and age of the snail and is between 100 to 500 eggs. Giant African snails have no specific season of mating, as they are able to produce new clutches every two to three months. One particularly problematic species is the Giant African snail (Achatina fulica), which is a devastating pest of farms and gardens in tropical and subtropical regions. It is an opportunistic, omnivorous and voracious eater which can consume 10% of its own weight daily (Schreurs, 1963).Also A.bstract. The Giant African snail (Achatina fulica) is a major pest in tropical countries. Current control methods involve the use of slug pellets (metaldehyde) but they are ineffective, therefore new methods of control are needed. The giant African land snail L. fulica is a fast-growing polyphagous plant pest that has been introduced from its native range in East Africa to many parts of the world as a commercial food source (for humans, fish and livestock) and as a novelty pet.. fulica is one of four species of giant African snails, 30 tonnes of which are collected each year in Togo (Ekoue and Kuevi-Akue, 2002). Integrated Pest Management. Ultimately, if control against L. fulica is to be effective it will have to involve some form of integration of the above methods. The giant African snail is a macrophytophagous herbivore; it eats a wide range of plant material, fruit, and vegetables. It will sometimes eat sand, very small stones, bones from carcasses and even concrete as calcium sources for its shell.he shell has a conical shape, being about twice as high as it is broad.

Giant African snails have no specific season of mating, as they are able to produce new clutches every two to three months. Egg sizes differ between species, from a 3 mm diameter in the grove snail to a 6 mm diameter in the Giant African Land Snail. After 2 to 4 weeks of favorable weather, these eggs hatch and the young emerge. Snails may lay eggs as often as once a month.n the wild, snails eat a variety of different foods. Terrestrial snails are usually herbivorous, however there are some species that are predatory carnivores or omnivores. The diet of most land snails can include leaves, stems, soft bark, fruit, vegetables, fungi and algae. Tiger Snail, Giant Ghana Snail.
