The Himalayan relict dragonfly is one of four species of Epiprocta in the family Epiophlebiidae. They have at one time been classified as a suborder Anisozygoptera, considered as intermediate between the dragonflies and the damselflies, partly because the hind wings and fore wings are very similar in size and shape, and partly because the insect at rest holds them back over the body as damselflies do. These attributes now are known to be misleading however; the genus Epiophlebia shares a more recent ancestor with dragonflies and became separated from other Anisoptera in and around the uplifting Himalayas.
Opisthostoma is a genus of minute land snails with opercula, terrestrial gastropod mollusks or micromollusks in the family Diplommatinidae.
Opisthostoma fraternum is a species of minute land snail with an operculum, a terrestrial gastropod mollusk in the family Diplommatinidae. It is endemic to Malaysia. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.
Opisthostoma mirabile is a species of air-breathing land snail with an operculum, a terrestrial gastropod mollusk in the family Diplommatinidae.
A land snail is any of the numerous species of snail that live on land, as opposed to the sea snails and freshwater snails. Land snail is the common name for terrestrial gastropod mollusks that have shells. However, it is not always easy to say which species are terrestrial, because some are more or less amphibious between land and fresh water, and others are relatively amphibious between land and salt water.
Diplommatinidae is a family of small land snails, also known as staircase snails, with an operculum, terrestrial gastropod mollusks in the superfamily Cyclophoroidea. The Cochlostomatinae Kobelt, 1902, were previously considered a subfamily of the Diplommatinidae, but are now known to be a separate family.
Chorus giganteus is a species of sea snail in the family Muricidae. It is endemic to the coast of Chile, where it occurs from Antofagasta (23° S) to the south of the country at depths of 8–30 metres (26–98 ft). It is a benthic predator that lives on rocks in temperate waters. It has been overexploited by local fishermen in much of its range.
Slug, or land slug, is a common name for any apparently shell-less terrestrial gastropod mollusc. The word slug is also often used as part of the common name of any gastropod mollusc that has no shell, a very reduced shell, or only a small internal shell, particularly sea slugs and semislugs.
Frank Fortescue Laidlaw (1876–1963) was a British biologist, working particularly in the fields of entomology, herpetology, and malacology.
Amphidromus atricallosus is a species of air-breathing, arboreal land snail, a terrestrial pulmonate gastropod mollusk in the family Camaenidae.
Bruggennea is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Streptaxidae.
Snail slime (mucopolysaccharide) is a kind of mucus produced by snails, which are gastropod mollusks. Land snails and slugs both produce mucus, as does every other kind of gastropod, from marine, freshwater, and terrestrial habitats. The reproductive system of gastropods also produces mucus internally from special glands.
Atopos is a genus of carnivorous air-breathing land slugs, terrestrial pulmonate gastropod mollusks in the family Rathouisiidae.
Plectostoma concinnum is a species of air-breathing land snail with an operculum, a terrestrial gastropod mollusk in the family Diplommatinidae.
Plectostoma sciaphilum was a species of land snail in the family Diplommatinidae. This species was originally found on a single limestone karst at Bukit Panching, in Peninsular Malaysia. In 2007, this karst was quarried, thus destroying the only known site of occurrence for this species. Plectostoma species are allopatric, being in found in dozens of isolated karst hills where few species occur, meaning that limited gene flow exists and only negligible hybridization occurs. Shell is distinctly convex, tuba shape similar to that of Plectostoma senex and P. turriforme, but this species lacks basal constriction teeth. Shell height: 2.6–2.9 mm, width: 1.5–1.6 mm.
Plectostoma obliquedentatum is a species of air-breathing land snail with an operculum, a terrestrial gastropod mollusk in the family Diplommatinidae.
Endothyrella plectostoma is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Plectopylidae.
Plectostoma is a genus of air-breathing land snails in the family Diplommatinidae.
