Describe the Body of
a Segmented Worm
Segmented worms have long and narrow
bodies made of many linked sections called
segments.
These worms also have a head end and a tail
end, meaning they are bilateral symmetry.
Some of the segmented worms look like
flatworms and roundworms, which are:
cylindrical bodies and jelly-like.
Method of
Reproduction
Segmented worms can reproduce sexually and
asexually.
When a segmented worm reproduces sexually,
it meets with another worm in order to mate
and exchange sperm.
On the other hand, when a segmented worm
reproduces asexually, it would break into
pieces to duplicate.
Feeding Methods
Segmented worms are scavengers, they search
for food such as: soft fruit, decayed plants, and
animal remains.
On damp nights, these worms come up and
out of their burrows to begin their scavenger
hunt.
When the worms find food, they drag it down
into their burrows and eat it.
Defense Methods
Segmented worms have sense organs in their brain,
causing them to detect moving objects quickly, and
they can send messages back and forth to each other.
When the worm senses vibrations of footsteps, they
quickly go to their burrow underground, and hide for
protection.
Some of these worms sit-&-wait in their burrow and
they are ready to attack any animal that comes too
close.
Movement
Segmented worms move through their burrow
by using their well-developed muscles.
The worm’s stiff bristles stick out from each of
the worm segments.
In order to crawl forward, the worm sticks it’s
bristles in the ground and pulls itself along.
The Closed
Circulatory System
Segmented worms have a closed circulatory
system, like humans.
The closed circulatory system can move blood
around an animal’s body much more quickly
than an animal with an open circulatory
system.
The blood quickly carries oxygen and food to
the cells. Blood only moves within a connected
network of blood vessels.
