Do sea shells grow or do they stay the same size?
Yes they all grow.



On one of those shells that goes in a spiral the spiral gets bigger.



And on a shell like an oyster you can see the shell has got bigger as it is formed in rings.
Reply:All mollusks are stuck in their homes. The shells grow as the critter gets older and grows.
