Species of the family Ovulidae Fleming, 1822 are sometimes mistaken for seaslugs, especially when the shell is covered by the large colourful mantle. Let me quote Bill Rudman:
"One easy way to separate snails from slugs is to look for their eyes. If they are raised from the skin like this then they are a snail. If the eyes are embedded in the skin they are an opisthobranch."
