English: Partulina variabilis - Lanai tree snail, pupu kani oe
A member of the family Achatinellidae and the endemic Hawaiian subfamily Achatinellinae, is known only from the island of Lanai. The shell may coil to the right (dextral) or left (sinistral), but appears to be constant within a population. Adults may attain an age exceeding 15 to 20 years, and reproductive output is low, with an adult snail giving birth to 4 to 6 live young per year. There are no historical population estimates for this snail, but qualitative accounts of Hawaiian tree snails indicates they were widespread and abundant, possibly numbering in the tens of thousands between the 1800s and early 1900s. Surveys in 1994, 2000, 2001, and 2005 documented 55, 12, 4, and 29 individuals, respectively, in the lowland wet, montane wet, and wet cliff ecosystems in central Lanai. |
