Marine Life Shells on the Ocean Seabed
A smiling mermaid sits on the ocean floor next to a giant spiral seashell. The sea maiden marvels at the massive shell resting on the sea bed, taking in the unique shape of the large ocean treasure.
Ocean Mollusks and Giant Shell Formation
Seashells are hard protective outer skeletons created by marine mollusks such as snails, clams, and nautiluses to shield their soft bodies from predators. As the creature inside grows, it excretes calcium carbonate and proteins to enlarge the shell layer by layer in a spiral pattern. The largest living gastropod shell belongs to the Australian trumpet snail, which can grow up to three feet long in tropical ocean waters.
