Biocontrol out of control

The New Scientist web site recently posted this story about the unintended effects of the introduction of the rosy wolf snail (Euglandina rosea) to the island of Tahiti as a biological control for the invasive African land snail (Achatina fulica). It seems the predatory Euglandina has developed a taste for Partula snails, and has now wiped out 56 of the 61 species in that genus that lived on the island.
