Home, at last

Three species of the partula snail have found a new home on the island of Moorea, near Tahiti. The island happens to be the world's smallest nature reserve. The American predatory snail Euglandina rosea was the cause for the extinction of the three species: P suturalis , P taeniata and P tohiveana . The snails are now safe and secure in their home which is equipped with an electrified anti-snail fence and a salty moat. Out of the four sections of the reserve, each species has a separate home. The fourth section harbours all the three ( New Scientist , Vol 150, No 2033).
