Punctum blandianum is a species of minute air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Punctidae, the dot snails.
The shell of P. blandianum is between 1.1 and 1.3 mm wide. The outer shell surface has a sculpture of radial striae, which are obvious under magnification. The umbilicus is about one third the width of the shell. [1]
This species is found in the United States, in the states of Tennessee, Virginia and Alabama. [2]
Population sizes of Punctum blandianum have been observed to be five times larger on highly acidic sites than on basic sites. [3]
Gastropods, commonly known as slugs and snails, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda.
The decollate snail, scientific name Rumina decollata, is a medium-sized predatory land snail, a species of terrestrial pulmonate gastropod mollusk in the family Achatinidae. It is a European species that has been introduced in a number of areas worldwide.
Sea snail is a common name for slow-moving marine gastropod molluscs, usually with visible external shells, such as whelk or abalone. They share the taxonomic class Gastropoda with slugs, which are distinguished from snails primarily by the absence of a visible shell.
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.
Zonitoides arboreus, commonly known as the quick gloss snail, is a species of small air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Gastrodontidae.
Polygyridae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea.
Philomycidae are a family of air-breathing land slugs. They are terrestrial pulmonate gastropod mollusks in the superfamily Arionoidea.
Appalachina is a genus of small, air-breathing, land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae.
Discus rotundatus, common name rotund disc, is a species of small, air-breathing, land snail, a terrestrial pulmonate gastropod mollusk in the family Discidae, the disk snails.
Praticolella is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Polygyridae.
Lobosculum is a genus of small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Polygyridae.
The Helminthoglyptinae are a subfamily of air-breathing land snails, terrestrial pulmonate gastropod mollusks within the family Xanthonychidae.
Vallonia pulchella, common name the lovely vallonia, is a species of very small air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Valloniidae.
Punctum pygmaeum is a species of very small, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Punctidae, the dot snails.
Punctum is a genus of very small air-breathing land snails, terrestrial pulmonate gastropod mollusks or micromollusks in the subfamily Punctinae of the family Punctidae, the dot snails.
Freshwater snails are gastropod mollusks that live in fresh water. There are many different families. They are found throughout the world in various habitats, ranging from ephemeral pools to the largest lakes, and from small seeps and springs to major rivers. The great majority of freshwater gastropods have a shell, with very few exceptions. Some groups of snails that live in freshwater respire using gills, whereas other groups need to reach the surface to breathe air. In addition, some are amphibious and have both gills and a lung. Most feed on algae, but many are detritivores and some are filter feeders.
Punctum minutissimum is a species of minute air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Punctidae, the dot snails.
Punctum randolphi is a species of minute air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Punctidae, the dot snails.
Vallonia perspectiva or thin-lip vallonia is a species of small, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Valloniidae.
