An Giant Invader, African land snail. (10 Pics)

Compartir

The East African land snail, or giant African land snail, scientific name Achatina fulica, is a species of large, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Achatinidae.

As they develop rapidly and produce large numbers of offspring, this mollusc is now listed as one of the top 100 invasive species in the world.

It is a voracious feeder, and recognized as a serious pest organism affecting agriculture, natural ecosystems, commerce, and also human health.

In the wild, this species often harbors the parasitic nematode Angiostrongylus cantonensis, which can cause a very serious meningitis in humans. Human cases of this meningitis usually result from a person having eaten the raw or undercooked snail, but even handling live wild snails of this species can infect a person with the nematode and cause a life-threatening infection.
