What happened

The record, in order.

The Euglandina snail was released against the giant African snail and spread across Moorea at about 1.2 km a year, a 1984 Pacific Science study reported.

By 1987 all nine endemic Partula tree-snail species of Moorea were extinct in the wild, according to the University of Hawaii source.

Control of the giant African snail could not be shown, the same source says.
