Planorbis corinna is a species of minute, air-breathing freshwater snail, an aquatic pulmonate gastropod mollusc, or micromollusc in the family Planorbidae, the ram's horn snails, or planorbids. All planorbids have sinistral or left-coiling shells.

This species is endemic to New Zealand. [1]

Shell description

This species, like all planorbids, has a sinistral shell. The shell in this species is very minute, discoidal, with four slowly increasing whorls. The shell coloration is greenish-white to light brown. The width of the shell is up to 3.3 mm, and the height is up to 0.8 mm.

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.

Neoplanorbis smithi was a species of small freshwater snail, an aquatic gastropod mollusk in the family Planorbidae, the ramshorn snails. This species was endemic to the United States; it is now extinct. The shells of this species appear to be dextral in coiling, but as is the case in all planorbids, the shell is actually sinistral. In life the shell was carried upside down with the aperture on the right, and this makes it appear to be dextral.
