Life Cycles and Life Expectancy
In Tuck Everlasting, the Tucks lived forever because
they drank the water from the stream. In real life, all animals, including
humans, have a life cycle. On this web page you can find information
about life cycles and life expectancy.
We start out as a tiny cell. Between the ages of 11-13,
we start to develop into adults. This is called puberty. At the ages
of 60-70 we start showing ageing. It takes longer for the wrinkles and
tears on our body to go away. Your skin starts to wrinkle and you start
to get gray hair and then you die.
Her babies are eggs for 6-21 days.
After that they hatch and they are called tadpoles. They are tadpoles
7-10 days. Then they start to get hungry they start feeding on algae.
After about 6-9 weeks they get cute tiny legs. After about 9 weeks they
are like child frogs. After 12 weeks they become adult frogs.
The snake lays eggs in a rotten tree stump. Inside its eggs
the young feeds on the yolk until it grows big enough. It stays in the
egg for eight weeks incubating. Then the snake cuts a slit in the shell
of the egg using its tooth. The sharp piece of its bone is called the
snout. Some snakes give live birth.
The female butterfly lays spiky eggs on a cabbage leaf. It
takes about a week for them to hatch. When they hatch they are called
caterpillars or larva eating cabbage leaves. When they get fat and
are not hungry any more they spin silk cocoons around them and hang
upside down. And then they start metamorphosing. In the cocoon the body
is broken down into new organs and tissue and then it forms in to a butterfly.
