The shells allow the molluscs to survive in harsh conditions and withstand the tremendous pressure of the seabed. This ability to provide optimal protection has prompted engineers to investigate their form and structure in order to design vehicles and buildings to protect the people in them.
Consider the following: Engineers analyzed two types of shells – two-shell and spiral-shaped.
In bivalves it was found that ribbing on the outside directed the pressure to the joint and to the edges of the sink. On the other hand, the curved shape of the spiral shell directs pressure to its core and to its wider part. In both cases, due to the shape of the shells, the pressure is transferred to their healthiest parts, making the mollusc less likely to suffer injury.
Scientists conducted comparative tests by applying pressure to real shells and ordinary hemispheres and cones (made with a 3D printer) that resembled the shape and composition of the shells. The results revealed that the complex surface of the shells almost doubled their ability to withstand pressure compared to ordinary forms.
About the application of this study, the magazine say, “If you drive a shell-shaped car one day, it will be both attractive and designed to protect passengers.”

What do you think? Did the shape of the shells appear as a result of evolution, or was it conceived?

They were conceived the way they are – my opinion
You think they have no change.
I think the environment has a huge effect. Very interesting post.
Everyone adjusts to the environment – even us humans.
I think the shape of the shells has changed depending on the environmental conditions! Lovely photo.
I share the same opinion.
This is so interesting! I would believe that they adapted to the enviorment as many species do.
I was also interested in this article
Wonderful shot and very interesting info. I assume the shell was already conceived.
I think they change as a result of their adaptation to the environment in which they live.
