Rotadiscus is a genus of small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Charopidae.
Species within the genus Radioconus include:
A truffle is the fruiting body of a subterranean ascomycete fungus, predominantly one of the many species of the genus Tuber. In addition to Tuber, over one hundred other genera of fungi are classified as truffles including Geopora, Peziza, Choiromyces, and Leucangium. These genera belong to the class Pezizomycetes and the Pezizales order. Several truffle-like basidiomycetes are excluded from Pezizales, including Rhizopogon and Glomus. Truffles are ectomycorrhizal fungi, so they are usually found in close association with tree roots. Spore dispersal is accomplished through fungivores, animals that eat fungi. These fungi have significant ecological roles in nutrient cycling and drought tolerance.
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.
Lycopodium is a genus of clubmosses, also known as ground pines or creeping cedars, in the family Lycopodiaceae. Two very different circumscriptions of the genus are in use. In the Pteridophyte Phylogeny Group classification of 2016, Lycopodium is one of nine genera in the subfamily Lycopodioideae, and has from nine to 15 species. In other classifications, the genus is equivalent to the whole of the subfamily, since it includes all of the other genera. More than 40 species are accepted.
Potamopyrgus is a genus of minute freshwater snails with an operculum, aquatic gastropod molluscs or micromolluscs in the family Tateidae.
Blanus, also known as worm lizards, are a genus of amphisbaenians found in the Mediterranean region of Europe and North Africa. Like other amphisbaenians, Blanus species are specialized for a subterranean existence, with long, slender bodies, reduced limbs, and rudimentary eyes. Their skulls are powerfully constructed, allowing them to push through soil to create a burrow. Their jaws are well-developed, with large, recurved teeth and a pair of canine-like teeth in the upper jaw.
Stygobromus is a genus of amphipod crustaceans that live in subterranean habitats. The majority of the listed species are endemic to North America, a smaller number of species are also known from Eurasia. Most of the North American species live in areas which were not covered by the Laurentide Ice Sheet, although a few species seem to have survived under the ice. A number of species are on the IUCN Red List as endangered species (EN) or vulnerable species (VU); one species, S. lucifugus, is extinct.
Helicodiscidae is a family of small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Punctoidea.
Charopidae is a taxonomic family of small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Punctoidea.
Cavefish or cave fish is a generic term for fresh and brackish water fish adapted to life in caves and other underground habitats. Related terms are subterranean fish, troglomorphic fish, troglobitic fish, stygobitic fish, phreatic fish and hypogean fish.
Pupinidae is a taxonomic family of land snails with an operculum, terrestrial gastropod mollusks in the superfamily Cyclophoroidea.
Smeagol is a genus of small air-breathing sea slugs of the upper intertidal zone. They are pulmonate gastropod mollusks related to land slugs and snails.
Lucilla is a genus of very small air-breathing land snails, terrestrial pulmonate gastropod mollusks or micromollusks in the family Helicodiscidae.
Cytora is a genus of very small air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Pupinidae. This genus is endemic to New Zealand.
Nocticola is a genus of cockroaches in the family Nocticolidae distributed in Africa, south-east Asia and Australia. Nocticola are different from every other cockroach in that they are not infected with Blattabacterium cuenoti. This makes them the only genus in Blattodea that do not have the bacteria.
Iphitus is a genus of small sea snails, marine gastropods in the family Epitoniidae of the superfamily Epitonioidea, the wentletraps, the purple snails, and their allies.
Hadopyrgus ngataana is a tiny, transparent, and critically endangered freshwater snail, found only in a single stream in a cave in New Zealand.
Hadopyrgus is a genus of white or transparent freshwater snails found only in New Zealand. They are micromolluscs, just a few millimetres long, in the gastropod family Tateidae. Hadopyrgus species are subterranean – living in caves, underground aquifers, or deep in river gravels – and so were named from the Greek hades (underworld) and pyrgos (tower). They can have quite restricted ranges: Hadopyrgus ngataana, for example, has been found in just one pool, in a stream flowing through a single cave.
Catapyrgus is a genus of gastropods belonging to the family Tateidae.
Nepenthes pudica is a tropical pitcher plant known from a handful of localities in the Mentarang Hulu district of North Kalimantan, Borneo, where it occurs at 1100–1300 m above sea level. It is notable for producing achlorophyllous subterranean stems bearing functional underground pitchers; very few pitchers are produced above ground.
Horatia is a genus of gastropod molluscs, comprising a small group of minute stygobiont freshwater snails with valvatoid shells, belonging to the subfamily Horatiinae of the family Hydrobiidae.
