Distribution in scandinavian waters
Maximum length: 7 cm.
Depth: 0-1 m.
Environment: Commonly found on cliffs, rocks and large boulders
within the surf zone in the outer archipelagoes of Bohuslän on
the Swedish west coast. The limpet shell is usually postioned with a
few millimetres gap from the substrate and thus enabling water to flush
through its gills. If disturbed, the limpet will adhere itself firmly
against the substrate and became very difficult to remove. During daylight
hours the limpet remains stationary, but during the night can wander
several metres looking for food and there after return to its original
position. In reality, a tidal
creature, it will creep around and scrape microscopic algae off the
rocks with its tongue and after every excursion return to its favourite
haunt where its shell fits so snugly onto the substrate that removal
is almost impossible without breaking its shell.
