Mollusc shell repair marks as indicator of predator-pray interaction

This paper is an attempt to explain biomechanical function of gastropod shell ornamentation at the viviparid example. Ornamentation of the external shell surface usually increases shell strength, but ornamentation in specific morphological characters can be functional in many different ways and it can be very difficult, or almost impossible to determine its function. Some morphological features protect gastropod shell against crushing, others from peeling or sinking in the soft sediment.
