THE WEEK, Page 24HEALTH & SCIENCEThese Ain't Escargots
A slither of invaders threatens the continental U.S.
It began as a scam. Several crates, all innocently marked
"Reptiles," were flown from Lagos, Nigeria, to the U.S. Their
secret cargo: 1,000 Giant African Snails, considered by experts
to be the most dangerous land snail in the world. By the time
authorities knew they were in the country, the gastropods had
slipped out to animal dealers in 25 states from Florida to
Montana.
The baseball-size pets sell for about $10. To the right
owner they provide sensitive, undemanding companionship. But if
any of the Giant Africans are the same species that terrorized
Florida for several years during the 1970s, they can also cause
disaster on a biblical scale. Sexually mature at the age of five
months, a single pregnant, hermaphroditic snail can, if it
escapes to the wild, give rise to as many as 16 quadrillion
descendants in five years. Armed with 80,000 rasping teeth and
weighing up to a pound, each of these offspring can wade through
an entire head of lettuce at one sitting. "It eats anything,"
says University of Michigan zoologist J.B. Burch. House paint.
Dead Rats. Beer. Describing an infestation in Ceylon early in
this century, a British explorer wrote, "The huge snails were
to be seen -- literally in millions -- crawling over the ground,
climbing up walls, fences, and poles." The few Giants that have
been captured by the feds thus far appear to be a less prolific
variety, but the Department of Agriculture is still trying
frantically to round up the animals. "Anyone with Giant African
Snails in their possession should not turn them loose," pleads
an alarmed official. "They should turn them in."
