Partula is a
Many species of Partula are known under the general common names "Polynesian tree snail" and "Moorean viviparous tree snail".[4] Partulids are distributed across 5,000 sq mi (13,000 km2) of Pacific Ocean islands, from the Society Islands to New Guinea.[citation needed]
Once used as decorative items in Polynesian ceremonial wear and jewelry, these small snails (averaging about one-half to three-quarters of an inch in length) gained the attention of science when Dr. Henry Crampton (along with Yoshio Kondo) spent 50 years studying and cataloging partulids, detailing their remarkable array of morphological elements, ecological niches, and behavioral aspects that illustrate adaptive radiation.[5][6]
Decline
The partulids of the island of Tahiti act as an example of the possible deleterious effects of attempted biological control. After an infestation of the introduced giant African land snails (Achatina spp.), the carnivorous Florida rosy wolfsnail (Euglandina rosea) was introduced into Tahiti in an attempt to combat the African species.
The wolfsnail chose instead to hunt and eat members of the nearly 76 species of Partula that were endemic to Tahiti and the nearby islands, devouring all but 12 species in a decade. Several scientists recognized what was going on, and were able to save 12 species prior to their becoming
Today, the Zoological Society of London runs the Partula Programme Consortium which maintains a captive-breeding programme in the United Kingdom, France, and the United States.
The 2008
Individuals are being reintroduced to Tahiti from captive breeding programmes since 2014.[10][11] In April 2023, over 5,000 individual snails from zoos in the United States and the United Kingdom were released on Tahiti and Mo'orea.
