The Turtle and the Hellgrammite

advertisement
A presentation by Asher and Raven
• The first known existence of turtles is about 200 million years
ago.
• Turtles are reptiles.
• Turtles lay their eggs on land.
• Several species of turtle can live
to be over 100 years old,
including the American Box turtle.
• Turtles will live in any climate warm enough for them to
complete their breeding cycle.
• The shell of a turtle can contain more than 60 bones!

Turtles have a very distinct
factor about them: Their shell, of
course! Full grown turtles can
range from 4” to about 9’ and
live in or around bodies of
water, and are green to hide
within the vegetation.

What a turtle eats depends
almost entirely of where and
what type of turtle it is. Some
small turtles are carnivorous,
but as they mature they start
to have a more open,
omnivorous diet.

The life cycle of a turtle is egg,
child and adult. When the
mature, female turtles lay their
eggs and the life cycle
repeats.
• The dobsonfly lays eggs in water which
them hatch in their larvae, or the
hellgrammite.
• Dobsonflies live most of their life in water
as hellgrammites.
• The larvae can reach up to 3”, nearing
the end of their aquatic life.
• As a grown dobsonfly, male’s jaws can
become so big that they do not have the
leverage to break skin!

• Hellgrammites are dobsonfly
larvae, and they aren’t that
pretty. They have large
pinchers that can break human
skin, if not too big. Their shell,
while a larva, is composed of
many different plates, almost
like armor.

While larva, dobsonfly eat other
fly larva. While adults, it is
believed they do no eat at all.
If you were a dobsonfly, your
life would start when you are
an egg in the shallow water,
under a rock. After that you
would hatch and live under
water, until one day, you
would molt and emerge into
the world above. Almost
immediately, you lay your
eggs in the water, and then fly
off into the world where you
will die, and the life cycle
repeats.
