Hymenolepis diminuta, also known as rat tapeworm, is a species of Hymenolepis tapeworm that causes hymenolepiasis. It has slightly bigger eggs and proglottids than H. nana and infects mammals using insects as intermediate hosts. The adult structure is 20 to 60 cm long and the mature proglottid is similar to that of H. nana, except it is larger.
Henry Edward Crampton was an American evolutionary biologist and malacologist who specialized in land snails. Crampton undertook the first major study of evolution in nature in his research in the Society Islands. Crampton made twelve separate expeditions over the course of his career to Moorea near Tahiti to study the land snail genus Partula, while years more were spent measuring and cataloguing his specimens. In all, he dedicated nearly half-a-century to the study. Crampton taught as a professor at Columbia University and Barnard College from 1904 to 1943. He also worked as a curator at the American Museum of Natural History.
A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as only consisting of living members kept in captivity or as a naturalized population outside its historic range. Classification requires exhaustive surveys conducted within the species' known habitat with consideration given to seasonality, time of day, and life cycle. Once a species is classified as EW, the only way for it to be downgraded is through reintroduction.
Partula dentifera is an extinct species of air-breathing tropical land snail, a terrestrial pulmonate gastropod mollusk in the family Partulidae.

The species was officially listed as extinct by the International Union for Conservation of Nature in June 2024.

Partula langfordi was a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Partulidae. This species was known by the common name Langford's tree snail and endemic to the Northern Mariana Islands. It was recently declared extinct by the International Union for Conservation of Nature in June of 2024.
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.
Partula taeniata, common name the Moorean viviparous tree snail, is a species of terrestrial gastropod in the Partulidae family. It is endemic to French Polynesia.
Partula tristis is a species of air-breathing tropical land snail, a terrestrial pulmonate gastropod mollusk in the family Partulidae. This species was endemic to Ra'iātea, French Polynesia. It is now extinct. It is informally known as the mournful tree snail.
