Barleeiidae (often also spelled Barleeidae) is a family of minute sea snails, micromollusks in the clade Littorinimorpha. [1]
These snails are very abundant and live in sublittoral and intertidal waters on rocky substrates.
The shells are conical to high-spired. Their inner shell layer is chitinous. They are further characterized by a foot with sometimes a posterior mucous gland. Their olfactory organ, the osphradium is enlarged. In some species there are oesophageal pouches present. Their penis is sometimes provided with prostatic tissue. Their oviduct glands show a simple histology. [2]
Few malacologists are currently working on micromollusks. Since they are so small (only a few millimeters in size), they are difficult to study and classify. Therefore, these small mollusks are less well known than the larger ones.
Genera in the family Baleeiidae include:
Barleeia, or the barleysnails, is a genus of very small sea snails. They are marine gastropod micromollusks in the family Barleeiidae. These snails are usually only a couple of millimeters in length.
Rissooidea, originally named Rissoacea by Gray, 1847, is a taxonomic superfamily of small and minute marine snails, belonging to the clade Littorinimorpha.
Pyramidellidae, common name the pyram family, or pyramid shells, is a voluminous taxonomic family of mostly small and minute ectoparasitic sea snails, marine heterobranch gastropod molluscs. The great majority of species of pyrams are micromolluscs.
Cystiscidae is a taxonomic family of minute sea snails, marine gastropod mollusks or micromollusks.
Solariellidae is a family of small sea snails, marine gastropod mollusks in the superfamily Trochoidea.
Iravadiidae is a family of minute sea snails, marine gastropod molluscs in the superfamily Truncatelloidea and the clade Littorinimorpha.
Coralliophilinae is a taxonomic group, a subfamily of about 200–250 sea snails, marine gastropod mollusks commonly known as the coral snails or coral shells. This is a subfamily within the very large family Muricidae, the murex or rock snails.
