Helicina orbiculata

Helicina orbiculata, also known as Helicina (Oligyra) orbiculata and as Oligyra orbiculata, is a species of land snail with an operculum, a terrestrial gastropod mollusk in the family Helicinidae. They are one of few land snails to have eyes at the base of their tentacles. This may suggest Helicina Orbiculata individuals are separate male and female, as opposed to the usual hermaphroditic snail.
