A snail is, in loose terms, a shelled gastropod. The name is most often applied to land snails, terrestrial pulmonate gastropod molluscs. However, the common name snail is also used for most of the members of the molluscan class Gastropoda that have a coiled shell that is large enough for the animal to retract completely into. When the word "snail" is used in this most general sense, it includes not just land snails but also numerous species of sea snails and freshwater snails. Gastropods that naturally lack a shell, or have only an internal shell, are mostly called slugs, and land snails that have only a very small shell are often called semi-slugs.
Euchondrus is a genus of very small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Enidae.
Hydrocenidae is a taxonomic family of minute land snails or cave snails with an operculum, terrestrial gastropod mollusks or micromollusks in the clade Cycloneritimorpha.
The tooth-billed pigeon, also known as the manumea, is a large pigeon found only in Samoa. It is the only living species of genus Didunculus. Phylogenetic studies indicate that it is the most basal living member of the clade Columbidae. A related extinct species, the Tongan tooth-billed pigeon, is only known from subfossil remains in several archeological sites in Tonga. The tooth-billed pigeon is the national bird of Samoa and featured on the 20 tālā bills and the 50 sene pieces of the 2008/2011 series.

A love dart is a sharp, calcareous or chitinous dart which some hermaphroditic land snails and slugs create. Love darts are both formed and stored internally in a dart sac. These darts are made in sexually mature animals only, and are used as part of the sequence of events during courtship, before actual mating takes place. Darts are quite large compared to the size of the animal: in the case of the semi-slug genus Parmarion, the length of a dart can be up to one fifth that of the semi-slug's foot.
Anostoma, common name the up-mouth snails, is a genus of tropical air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Odontostomidae. Snails in this genus are found in Brazil.
Indrella is a monotypic genus containing the single species Indrella ampulla, a tropical terrestrial air-breathing gastropod mollusk in the family Ariophantidae. It is endemic to the Western Ghats of India.
Coninae, or as it is more recently represented as a family, Conidae, common names the cone snails, cone shells or cones, is a taxonomic group of small to large predatory sea snails with cone-shaped shells, marine gastropod mollusks in the superfamily Conoidea.
Gagadon is an extinct genus of even-toed ungulate that lived in the early Eocene of North America. The type and only known species, Gagadon minimonstrum, was described in 2014 based on lower teeth and jaw fragments found in the Wasatch Formation of Bitter Creek, Wyoming. The genus is named in honor of the singer Lady Gaga, while the species name minimonstrum refers to the small size and presence of unusual cusps on the teeth.
