[5] However, the species was distributed more widely in prehistoric times, as fossil shells were found at three other localities on the shore (Bastia: Toga, Piana: Plage d'Arone, Bonifacio).

[6][7] It inhabits biotopes on granitic sands near the shore, with vegetation characterized by Crucianella maritima, Scrophularia ramosissima and Genista salzmannii ssp.

[4] During dry and hot periods, the snails dig up to 60 cm into the soil and form a convex, calcareous epiphragm.

[4] Helix ceratina feeds on fresh leaves in the spring, but the diet changes to decaying plant matter in the autumn.

Genista salzmannii is the most important part of the diet (found in 80% of faeces); Matthiola sinuata, Jasione montana and grasses are also eaten.
