|General Biology Additional Information||On rocky shores of wave exposure grade 1 (Ballantine scale: Ballantine, 1964), Patella ulyssiponensis occurs at densities of 1000 m² but individuals are small (Thompson, 1979). On less wave exposed shores density is lower but individuals are larger.
Patella ulyssiponensis is parasitised by Cercaria patellae, a trematode platyhelminth, which have infection levels of 5-10% in adults and can cause damage of the digestive gland. Gymnophallid metacercariae infect between the mantle and the shell and have an infection level of approximately 5%. The gut of Patella ulyssiponensis is sometimes infected by larval cyclophyllidean tapeworms (Kinne, 1980).
