Powelliphanta spedeni, known as one of the amber snails, is a species of large, carnivorous land snail, a terrestrial pulmonate gastropod mollusc in the family Rhytididae.
This species is endemic to the South Island of New Zealand. There are two subspecies: [1]
The shell of Powelliphanta spedeni reaches a maximum size of 40 mm. [2]
Powelliphanta spedeni produces an egg up to the size of 11.5 mm. [2] Shape of the eggs is oval and seldom constant in dimensions 11.5 × 9 mm, 11 × 9 mm, 9 × 7.75 mm. [2] Its eggs are laid in March. [2]
Powelliphanta is a genus of large, air-breathing land snails, pulmonate gastropods in the family Rhytididae, found only in New Zealand. They are carnivorous, eating invertebrates, mostly native earthworms. Often restricted to very small areas of moist forest, they are prey to introduced mammalian predators, and many species are threatened or endangered.
Rhytididae is a taxonomic family of medium-sized predatory air-breathing land snails, carnivorous terrestrial pulmonate gastropod molluscs in the superfamily Rhytidoidea.
Schizoglossa, common name the Paua slugs, is a genus of medium-sized to large predatory, air-breathing, land slugs, carnivorous terrestrial pulmonate gastropod molluscs in the family Rhytididae. They are currently classified by the New Zealand Department of Conservation as Nationally Vulnerable.
Paryphanta busbyi is a species of large predatory land snail, a terrestrial pulmonate gastropod mollusk in the family Rhytididae.
Powelliphanta superba is a species of large, carnivorous land snail in the family Rhytididae, which is endemic to the South Island of New Zealand. Five subspecies are recognised, all of which are classified by the New Zealand Department of Conservation as being Nationally Endangered.
Powelliphanta spedeni lateumbilicata, known as one of the amber snails, is a subspecies of large, carnivorous land snail, a terrestrial pulmonate gastropod mollusc in the family Rhytididae.
Powelliphanta annectens is one of the amber snails, an air-breathing land snail, a terrestrial gastropod mollusc in the family Rhytididae. It is a protected species with very limited distribution.
Powelliphanta augusta or the Mount Augustus snail, previously provisionally known as Powelliphanta "Augustus", is a species of large, carnivorous land snail, a terrestrial pulmonate gastropod mollusc in the family Rhytididae. Naturally occurring only on Mount Augustus near Westport on New Zealand's South Island, their entire habitat was destroyed by coal mining. The world population was taken into captivity, in theory until their habitat was restored and they could be released. The mining company concerned went bankrupt and habitat restoration has been unsuccessful, so the species' future is uncertain.
Powelliphanta rossiana, known as Ross' land snail, is a species of large, carnivorous land snail, a terrestrial pulmonate gastropod mollusc in the family Rhytididae. This species is endemic to the South Island of New Zealand. Subspecies include:
