Hi there,

Mollusks secrete (grow) a single shell that gets larger throughout their
life. Invertebrates with exoskeletons (like lobsters) shed their outer
shell so they can increase in size. Can't think of an equivalent to deer's
antlers right now ....

Subject: conchs

good afternoon,
i don't know if you are the right person to ask but i have a question. if
you can't answer it would you please direct to who could?
this past weekend my husband & i took our boys to the beach. we got up
early and went looking for sandollars. we only found a few of them but what
we did find lots of were conch shells. they had the animals (whatever you
call them) still in them. we have never found anything like that at the
beach we were visiting.
what i would like to know is, where do the shells come from & do the animals
find bigger ones as they get bigger? i was trying to think of it in
relation to a deer (very different i know) but a deer looses his antlers &
grows new one each year. i don't understand about the shells of fish.
i am no marine biology person, just curious.
can you help?
