†Partula faba (Gmelin, 1791)

Partula faba, commonly known as the bean snail,^[2] Partula snail,^[2] or Captain Cook's bean snail,^[3]^[a] is an extinct^[4] species of air-breathing tropical land snail, a terrestrial pulmonate gastropod mollusk in the family Partulidae. This species was endemic to Ra'iātea and Tahaa, neighbouring islands which share the same lagoon, in French Polynesia. The species was the first Partula to be recorded.^[4]

In captivity

From 1991 zoos in the United Kingdom fought to save this species from extinction. For a while this was successful but a slow decline set in. Bristol Zoo and then Edinburgh Zoo were entrusted with the last-known colony of these snails.^[5] This was not a success and the last snail died in February 2016.^[4]

Subspecies

The species contained two subspecies.

Partula faba ssp. faba – Raiatea
Partula faba ssp. subangulata – Tahaa

Reasons for decline

The introduction of the small carnivorous snail Euglandina rosea in the 1980s caused the decline of many native species of Partulidae, among them Partula faba.

Notes

^ Thomas Martyn, on the voyage of discovery with James Cook, named the snail Limax faba (bean snail) but left no record as to why.^[3]
