Title: How do shells grow?
Post by: turnipsock on 04/02/2008 22:44:16

Shells look pretty solid to me. On the shore, I can see very small mussels and very large mussels. How do they grow big?

All sea shells are the homes for the said creatures as your initial post says the Mussels
are Bivalves which are related to Clams and are edible too.
They are also Molluscs.
But for land creatures with shells such as garden snails, the same applys that their many
different shapes and patterns on their shells are each for a different mollusc as we have
our individual finger prints.

The shell is deposited by the bivalve's mantle. See http://www.assateague.com/nt-bival.html top picture, red x with line to the bottom of diagram.
