Partula mooreana, common name the Moorean viviparous tree snail, is a species of air-breathing tropical land snail, a terrestrial pulmonate gastropod mollusk in the family Partulidae. This species was endemic to French Polynesia. It is now extinct in the wild.
Partula mooreana was originally described by William Dell Hartman (1817–1899) in 1880. [2] Hartman's original text (the type description) reads as follows:
Partula Mooreana, Hartman.
Shell sinistral, ovate, elongate, thin, translucent, pale yellowish horn-color, apex darker; whorls 5, flatly convex, body whorl, with or without from one to three narrow, pale, brown revolving bands; surface smooth, with fine, oblique striations, which are decussated by crowded waved spiral striae; a narrow white line beneath the suture; aperture hearly half the length of the shell, lip white, moderately reflected, pillar tooth oval, prominent, situated nearest the superior angle, umbilicus open, moderately compressed.
Length 18 mill., diameter 9 mill.
Hab. — Vaianai Valley, Island of Moorea (Andrew Garrett, Esq.).
In one hundred and forty-six species and varieties of Partula represented in my collection, this shell possesses constant and well-marked specific characters. Mr. Garrett informs me that fifteen hundred specimens were all sinistral and dentate. The surface of the shell resembles P. spadicea and varieties from Moorea in possessing the thickly crowded waved spiral striae.
This species is arboreal, and is not uncommon on bushes, in
Vaianai Valley, the metropolis of P. vexillum Pse. = P. stenostoma Ph.
The gastropod shell is part of the body of a gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group.
Partula aurantia, common name the Moorean viviparous tree snail, was a species of air-breathing tropical land snail, a terrestrial pulmonate gastropod mollusk in the family Partulidae. This species was endemic to French Polynesia. It is now extinct.
Partula exigua, common name the Moorean viviparous tree snail, was a species of air-breathing tropical land snail, a terrestrial pulmonate gastropod mollusk in the family Partulidae. This species was endemic to the island of Moorea in French Polynesia. It is now extinct.
Partula mirabilis, common name the Moorean viviparous tree snail, is a species of air-breathing tropical land snail, a terrestrial pulmonate gastropod mollusk in the family Partulidae. This species was endemic to the island of Moorea, French Polynesia. It is now extinct in the wild.
Partula suturalis, commonly called the moorean viviparous tree snail or the sutural partula, is a species of air-breathing tropical land snail, a terrestrial pulmonate gastropod mollusk in the family Partulidae. This species was endemic to the island of Moorea, French Polynesia. It is now extinct in the wild. It was previously listed as extinct in the IUCN Red List of Threatened Species, but has been moved to extinct in the wild since 2009. This error was the result of changing taxonomy.
