Planorbarius corneus, common name the great ramshorn, is a relatively large species of air-breathing freshwater 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 shell of this species appears to be dextral in coiling, even though it is in fact sinistral or left-handed.

[edit] Habitat
This large planorbid is found in water which is still, or only moving slowly, where there is a good growth of many different kinds of pond weeds, and where there are high levels of calcium dissolved in the water.[6]
Planorbarius corneus under high temperatures has been studied by Kartavykh & Podkovkin (2002).[7]
[edit] Parasites
This species of snail functions as a host for several parasite species:

- as first intermediate host for Apatemon gracilis[9]
- as first and as second intermediate host for Hypoderaeum conoideum[10]
- as intermediate host for Syngamus trachea[11]
