How Seashells Take Shape Scientific American

How Seashells Take Shape Scientific American These projections form at regular periods in which the mantle undergoes a growth spurt. during a growth spurt, the mantle develops so quickly that it has an excess of length and cannot align with. Seashells are the exoskeletons of mollusks such as snails, clams, oysters and many others. such shells have three distinct layers and are composed mostly of calcium carbonate with only a small.

Mollusks have an outermost layer of tissue on their bodies. called the mantle, this layer connects the animal to its shell. the mantle also creates that shell. specialized cells in the mantle build the shell using proteins and minerals. these are secreted—released into the space outside the cells.
