Heteropod Atlanta peronii
The heteropod is a seafaring snail with a thin fragile shell containing only the heart and gills. It swims upside down, using its tiny shell as a keel. It has a toothy radula (tongue) in its long proboscis and is a voracious hunter, capable of devouring prey as large as itself.
