- Uses a radula to feed on algae
in the lower intertidal.
- For longer periods of exposure
a dried mucus seal forms around the shell opening
reducing evaporation.
- For longer periods of exposure
a mucus seal is secreted by the foot around the
shell opening, in essence glueing the shell to
the rock.
- Littorina littorea has
the ability to determine its position on the shore
relative to the preferred zone, can orient itself
in this direction and move into more suitable conditions.
- It demonstrates behavioral adaptations
to desiccation, seeking out damp crevices and forming
gregarious aggregations to reduce evaporative loss.

- Uses a radula to scrape algae from
the rocks.
- Laying egg masses on seaweed blades
and having young that can crawl away upon hatching
increase likelihood of survival.
- Shell color varies allowing for
camoflauge in their environment.
