Species:
Ham Hill is a hill and area of chalk downland in Wiltshire, England, on the steep banks running alongside the road from the village of Ham to Buttermere, close to the Berkshire border. A biological Site of Special Scientific Interest, notified in 1971, covers 1.5 hectares of the site; this designation is due to the site's species-rich plant and insect communities, which include some rare species. Notable among these is the musk orchid, which has been confirmed at only one other site in Wiltshire.
Bithyniidae is a family of small freshwater snails with an operculum, aquatic gastropod molluscs in the clade Littorinimorpha.
Beddomeia minima is a population of freshwater snails that are endemic to Australia. It is commonly classified as a hydrobiid snail. This population was listed as Vulnerable on the IUCN Red List in 2011 due to its distribution being restricted to a single location and range of possible threats present in Tasmania. Beddomeia minima is one of a few fresh water snail species belonging to the same genus Beddomeia that survive in Tasmania, Australia, specifically a single location in the Scottsdale area.
Assimineidae is a family of minute snails, also known as palmleaf snails, with an operculum, gastropod mollusks or micromollusks in the superfamily Rissoidae. Many of these very small snails live in intermediate habitats, being amphibious between saltwater and land; others live in freshwater.
Cyclophoroidea is a superfamily of land snails with an operculum, terrestrial gastropods within the informal group Architaenioglossa, that belongs to the clade Caenogastropoda.
Chrysomallon squamiferum, commonly known as the scaly-foot gastropod, scaly-foot snail, sea pangolin, or volcano snail is a species of deep-sea hydrothermal-vent snail, a marine gastropod mollusc in the family Peltospiridae. This vent-endemic gastropod is known only from deep-sea hydrothermal vents in the Indian Ocean, where it has been found at depths of about 2,400–2,900 m (1.5–1.8 mi). C. squamiferum differs greatly from other deep-sea gastropods, even the closely related neomphalines. In 2019, it was declared endangered on the IUCN Red List, the first species to be listed as such due to risks from deep-sea mining of its vent habitat.
Provannidae is a family of deep water sea snails, marine gastropod mollusks in the superfmaily Abyssochrysoidea.
Nipponacmea is a genus of sea snails, the true limpets, marine gastropod mollusks in the family Lottiidae.
Abyssochrysos is a genus of bathyal sea snails, marine gastropod mollusks in the family Abyssochrysidae.
British NVC community OV38 is one of the open habitat communities in the British National Vegetation Classification system. It is one of six communities of crevice, scree and spoil vegetation.
Marstonia comalensis is a species of minute freshwater snail with a gill and an operculum, an aquatic gastropod mollusk or micromollusk in the family Hydrobiidae. It is found in south central Texas, United States.
Ctenidium may refer to:
A ctenidium is a respiratory organ or gill which is found in many molluscs. This structure exists in bivalves, cephalopods, Polyplacophorans (chitons), and in aquatic gastropods such as freshwater snails and marine snails. Some aquatic gastropods possess one ctenidium known as monopectinate and others have a pair of ctenidia known as bipectinate.
Bathyacmaea nipponica is a species of very small, deep-sea limpet, a marine gastropod mollusk in the family Pectinodontidae.
Bryotropha dryadella is a moth of the family Gelechiidae. It is found in Great Britain, France, Portugal, Spain, Corsica, Sardinia, Sicily, Italy, Albania, North Macedonia, Bulgaria, Greece, Crete and Algeria.
Pinna rudis, the rough pen shell or spiny fan-mussel, is a species of bivalve mollusc in the family Pinnidae. It is the type species of the genus Pinna. Knowledge about this is sparse, with an absence of specific studies and literature.
Almargemia is a genus of fossil leaves from the Early Cretaceous of Portugal produced by members of the Zamiaceae. It was erected by Rudolf Florin based on macrofossil material with preserved cuticle.
Wilfred "Wilf" Borden Schofield was a Canadian botanist, specializing in mosses and liverworts. He was considered by many "the foremost bryologist in Canada".
Ctenidium molluscum is a species of moss belonging to the family Hypnaceae.
