• Norwegian: marmorleddsnegl


T. rubra reaches a length of 21 mm, considerably smaller than the similar T. marmorea. The the slightly narrower mantle is covered by oval granules. The shell makes approximately 75% of the animals width. The mantle is often banded with red/pink and orange/yellow bands. The valves are rounded with a moderate keel.


It is most frequent from lower shore to approximately 300 meters depth. As most chitons, it prefers rocky locations.


It is known from both Canada as well as the Arctic and North Europe, as far south as the British Isles.
