Biomphalaria havanensis, common name the ghost rams-horn, is a species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails.

The shell of this species, like all planorbids is sinistral in coiling, but is carried upside down and thus appears to be dextral.

Distribution

Biomphalaria havanensis is a Neotropical species.
