[1][2] This limpet occurs off the eastern Atlantic coasts from Iceland and Norway, to Portugal.

It is absent from the Baltic Sea, East Denmark, Belgium and the Netherlands.

[3] The blue-rayed limpet lives primarily on Laminaria (kelp) in strong flowing water[4] but also on Fucus serratus on the lower shore, down to about 30 m. The larvae of this limpet species settle and metamorphose on the algal frond.

Here it feeds on its host’s tissue using its radula, leaving small depressions in the frond.

As the limpets grow larger, they move down the stipe of the seaweed towards the holdfast, where they establish themselves by excavating a depression.
