Many snails live just one or two years. But some volutes like
Adelomelon brasiliana or Zidona dufresnei do live for about 17
years (according to a paper by Penchaszadeh) and the sexual
maturity takes about 7 years.

As my passion for shells has touched numerous other people, they
haveasked me, "How old is this, or that shell." I have no
idea.How old do shells grow to? I have not seen a
"small/babycone". Yet I do not believe they are born 50 mm
long. Where are allthe babies? For example, I never saw a
small Tiger Cowrie. Where arethey hiding? Can anybody give us
some insight?
