Bulinus is a genus of small tropical freshwater snails, aquatic gastropod mollusks in the family Bulinidae, the ramshorn snails and their allies.
Planorbidae, common name the ramshorn snails or ram's horn snails, is a family of air-breathing freshwater snails, aquatic pulmonate gastropod molluscs. Unlike most molluscs, the blood of ram's horn snails contains iron-based hemoglobin instead of copper-based hemocyanin. As a result, planorbids are able to breathe oxygen more efficiently than other molluscs. The presence of hemoglobin gives the body a reddish colour. This is especially apparent in albino animals.
Planorbella trivolvis is a species of freshwater air-breathing snail, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails, or planorbids, which all have sinistral or left-coiling shells.
The river limpet is a species of very small, freshwater, air-breathing limpet, an aquatic pulmonate gastropod mollusk in the tribe Ancylini within the family Planorbidae, the ram's horn snails and their allies.
Hovorbis rodriguezensis is a species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusc in the family Planorbidae, the ram's horn snails and their allies.
Africanogyrus is a genus of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails and their allies.
Biomphalaria salinarum is a species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails.
Bulinus nyassanus is a species of small air-breathing freshwater snail with a sinistral shell, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ramshorn snails and their allies. This species is endemic to Lake Malawi in Africa, where found both in shallow and relatively deep water. Its shell generally reached a size of up to around 14 mm × 11 mm.
Cleopatra grandidieri is a species of freshwater snails with an operculum, aquatic gastropod molluscs in the family Paludomidae.
Theodoxus numidicus is a species of small freshwater snail with an operculum, an aquatic gastropod mollusk in the family Neritidae, the nerites.
Ferrissia californica is a species of small freshwater limpet, an aquatic gastropod mollusk in the family Planorbidae.
Gyraulus chinensis is a species of small freshwater snail, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails.

Neritina pulligera, common name the dusky nerite, is a species of freshwater snail, a gastropod mollusk in the family Neritidae.
Indoplanorbis is a genus of air-breathing freshwater snail. Its only member species is Indoplanorbis exustus, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails. The species is widely distributed across the tropics. It serves as an important intermediate host for several trematode parasites. The invasive nature and ecological tolerance of Indoplanorbis exustus add to its importance in veterinary and medical science.
Bulinus tropicus is a species of a tropical freshwater snail with a sinistral shell, an aquatic gastropod mollusk in the family Bulinidae, the ramshorn snails and their allies.
Bulinus abyssinicus is a species of tropical freshwater snail with a sinistral shell, an aquatic gastropod mollusk in the family Planorbidae, the ramshorn snails and their allies.
Bulinus obtusispira is a species of a tropical freshwater snail with a sinistral shell, an aquatic gastropod mollusk in the family Planorbidae, the ramshorn snails and their allies.
Hovorbis is a genus of air-breathing freshwater snails in the family Planorbidae, the ram's horn snails and their allies.
