Reproduction
Lymnaeid snails are hermaphrodites, which means they have
both male and female reproductive organs and are able to
self-fertilize if necessary, though finding a mate is preferable
for genetic variation (EOL). The snails lay eggs, in which the
embryonic offspring complete their development, emerging as
miniature adults (EOL). In other words they have a direct life cycle
with no larval stages. Their life cycle is strongly influenced
by temperature. The typical range for reaching maturity is 9-15
months, though in warmer waters they can complete more than one
generation per year. In colder waters maturation may take
several years (EOL).
