Planorbidae

page 1

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.

Burnupia is a genus of small freshwater snails or limpets, aquatic gastropod mollusks. It was formerly placed in the family Planorbidae, but according to the molecular markers (COI, 18S rRNA), it is in a different clade than the genera of the family Planorbidae. It is now classified in the monotypic family Burnupiidae.

Drepanotrema is a genus of molluscs in the family Planorbidae. Two subgenera, Drepanotrema (Drepanotrema) Fischer & Crosse, 1880 and Drepanotrema (Fossulorbis) Pilsbry, 1934, have been eschewed in favour of the genus.
