Know the similarities and differences between the life cycle’s of the Burmese
Python and Garden Snail:

The life cycle of the Burmese Python:
o Three months after mating, the mother python lays eggs.
o The mother python stays wrapped around the eggs while they grow (she
never leaves the eggs).
o Six to eight weeks later, the eggs hatch.
o The mother python leaves the young to fend for themselves.
o Burmese pythons can live 25 years.

The life cycle of the Garden Snail:
o After mating, the mother snail lays eggs.
o The snail leaves before the eggs hatch.
o When the eggs hatch, the young fend for themselves.
o Snails live about 10 years.

Migration is traveling in search of food or a place to reproduce. Canadian geese
not only have the instinct to migrate, but do so to help them survive. Flocks of
geese migrate south to escape the cold winter weather and find food. They return
north in the spring.
