Giant African land snail

Lissachatina fulica

Also calledKonokono (Swahili) · Ghongha (Hindi) · Achatine (French) · Caracol gigante africano (Spanish) · Afurikamaimai (Japanese)

A fist-sized land snail from East Africa that has spread across the tropics and is listed among the world's worst invasive species. It eats hundreds of plant species, can lay over a thousand eggs a year, and can carry rat lungworm, a parasite that causes meningitis.

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. It is a federally prohibited species in the U.S., as it is illegal to sell or possess. Internationally, it is the most frequently occurring invasive species of snail. Wikipedia

§1

What it can do

  1. iEats more than 500 kinds of plants, as well as plaster and concrete for calcium
  2. iiLays clutches of 100–400 eggs several times a year
  3. iiiSurvives dry seasons by sealing its shell and becoming dormant for months
  4. ivHermaphrodite; can store sperm from a single mating for many months

In the field

Field marks

  • aLarge, tall, cone-shaped shell
  • bBrown to reddish-brown with darker vertical streaks
  • cSeven to nine whorls
  • dGrey-brown body with long tentacles
Not to be confused with
Giant Ghana tiger snail (Achatina achatina) is larger with bold zig-zag stripes. Rosy wolfsnail (Euglandina rosea) is smaller, pinkish, and predatory. Native apple snails (Pomacea) live in water and have a rounder shell.
Where to see it
Gardens and farmland across tropical Asia, Pacific islands and parts of Brazil; native forests of coastal Kenya and Tanzania.
When
Most active in the rainy season
§3

Life & habits

Diet
Crops, garden plants, fallen fruit, decaying matter, and calcium from walls and shells
Habitat
Farms, gardens, plantations and disturbed land in warm, humid regions
Size
Shell typically 7–10 cm long, up to about 20 cm
Lifespan
Usually 3–5 years; up to about 9 years

Active at night and after rain; in dry periods it hides in soil or under debris, sealed behind a mucus membrane.

In the old herbals & bestiaries

No plate in the Source Library names this exact species, so these show its closest relatives as the old naturalists drew them: same genus, or the same kind of animal. Click a plate to read the page it came from, with translation.

§7

Marginalia

It was carried from East Africa to Mauritius in the early 1800s and to India by the 1840s, then across Asia and the Pacific; in Florida a boy's three pet snails brought from Hawaii in 1966 led to a decade-long eradication campaign.

Curiosity

The rosy wolfsnail introduced to Pacific islands to eat it instead wiped out dozens of native Partula tree snails, a famous biological-control disaster.
