Short description Μορφολογία

Description: Color is usually gray-brown and white. Radiating ribs of shell are both light and dark. There is a small opening at the peak (Ref. 312).

Βιολογία     Γλωσσάρι (π.χ. epibenthic)

It has a shell length of 7 cm long (Ref. 312). Occurs at low intertidal zones. Omnivorous; encrusting bryozoans are sometimes consumed in preference to algae. When under attack by a sea star, it will extend its mantle flap over its foot and shell so that the tube feet of the star fish cannot grasp it (Ref. 312).

Life cycle and mating behavior Γεννητική Ωρίμανση | Αναπαραγωγή | Γεννοβολία | Eggs | Γονιμότητα | Larvae

Members of the order Patellogastropoda are mostly gonochoric and broadcast spawners. Life cycle: Embryos develop into planktonic trocophore larvae and later into juvenile veligers before becoming fully grown adults.
