Achatina achatina, commonly known as the giant African snail, also known as the giant tiger land snail, and gigantocochlea[ citation needed ] , is a species of large, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Achatinidae. The name "Achatina" is from "achates", Greek for agate. [1] It shares the common name "giant African snail" with other species of snails such as Lissachatina fulica and Archachatina marginata .

Subspecies

Distribution

The species is believed to be native to West Africa, within 160 kilometres (99 mi) to 300 kilometres (190 mi) of the coasts off Sierra Leone, Liberia, Ivory Coast, Togo, Benin, Ghana, and Nigeria.

Achatina achatina is routinely confiscated by quarantine authorities at United States airports, especially in Baltimore, Dulles International Airport in Washington, D.C., John F. Kennedy International Airport in New York, and San Francisco. [2] These large snails are kept as pets in the Western world, where owners prize their large size, distinctive markings, and rarity. [3]

It has been suggested that these species be given top national quarantine significance in the United States. [4]

Description

The shells of these snails often grow to a length of 18 centimetres (7.1 in) with a diameter of 9 centimetres (3.5 in). Certain examples have been surveyed in the wild at 30×15 cm, making them the largest extant land snail species known. [5] [6]

Similar to other giant land snails such as the Achatina fulica , Achatina achatinas are herbivores. Their diets consist of many plants such as nuts, flowers, fruit, stems, and leaves. Achatina achatina have also been known to eat farmers' crops including cocoa, peanuts, bananas, and cauliflower. [7]

In other instances, the giant African land snail has been known to eat smaller invertebrates in order to reach their desired calcium and protein intake needed for survival. Such insects include ants, small worms, beetles, and smaller snails.

Ecology

Like almost all pulmonate gastropods, these snails are hermaphrodites, having male and female sex organs. Each snail lays up to 1200 eggs per year. Achatina achatina is an important source of animal protein for West African forest-dwelling ethnic groups, and there is potential for commercial farming. [8]

This species' substantial size and potential for rapid population growth can make the snail a serious pest when introduced to non-native ecosystems. The population size of this species can be curtailed through disease caused by the bacterium Aeromonas hydrophila [9] but it often has no other natural enemies. [10]

<span class="mw-page-title-main">Snail</span> Shelled gastropod

A snail is a shelled gastropod. The name is most often applied to land snails, terrestrial pulmonate gastropod molluscs. However, the common name snail is also used for most of the members of the molluscan class Gastropoda that have a coiled shell that is large enough for the animal to retract completely into. When the word "snail" is used in this most general sense, it includes not just land snails but also numerous species of sea snails and freshwater snails. Gastropods that naturally lack a shell, or have only an internal shell, are mostly called slugs, and land snails that have only a very small shell are often called semi-slugs.

A land snail is any of the numerous species of snail that live on land, as opposed to the sea snails and freshwater snails. Land snail is the common name for terrestrial gastropod mollusks that have shells. However, it is not always easy to say which species are terrestrial, because some are more or less amphibious between land and fresh water, and others are relatively amphibious between land and salt water.
