In today's world, Sculpture (mollusc) is an issue that has gained relevance in society. With the advancement of technology and globalization, Sculpture (mollusc) has become a point of interest for many, generating debate and reflection in different areas. Whether in academia, work, or everyday life, Sculpture (mollusc) has impacted people around the world in various ways. In this article, we will further explore the impact of Sculpture (mollusc) and how it has influenced different aspects of modern life.
Sculpture can be concave or convex, incised into the surface or raised from it. Sometimes the sculpture has microscopic detailing. The term "sculpture" refers only to the calcareous outer layer of shell, and does not include the proteinaceous periostracum, which is in some cases textured even when the underlying shell surface is smooth.
In many taxa, there is no sculpture on the shell surface at all, apart from the presence of fine growth lines.
The sculpture has a protective function because it increases the diameter of the shell, distributing mechanical stress (such as the force of a predator's jaws) across a larger surface area.
