Partula turgida
Species of gastropod
†Partula turgida was a species of air-breathing tropical land snail, a terrestrial pulmonate gastropod mollusk in the family Partulidae. This species was endemic to Ra'iātea, French Polynesia. It died out in 1996, and is now extinct.[1] The snail's low rate of movement made it hard to determine the exact date of death but it was confirmed on 31 January.[2]
Partula turgida was being kept alive in captivity, when the population suffered a crash caused by the microsporidian genus Steinhausia. This is the first definitive report of an extinction of a species caused by a parasite.[3]
