We are found everywhere and are present on land, freshwater, and seawater.
Earthworms (Oligochaetes) are found on land, leeches (Hirudinomorphia) are present near freshwater streams, and marine worms (Polychaetes) live in the ocean.
All we require is a little moisture.
Earthworms constantly burrow through the ground searching for food, conveniently tilling the soil in the process.
The leeches are parasitic and steal from others to survive.
Marine worms deposit-feed or filter-feed, depending on where they are.
After it rains, I am able to survive above ground, however, I know many of my relatives have died on a strange black surface.
We have visible external segmentation, and our internal organs are repeated, so if we lose a few parts, we can still survive.
We have septa in between segments which can help distinguish them. Our epidermis has cuticle which prevents loss of water.
Our circulatory system is closed, allowing us to thrive in varying conditions.
What’s Special About Us
We have many, easily replaceable segments. By keeping them simple and having multiple copies, any damaged section can be replaced rapidly.
The cuticle prevent the loss of water from the internal environment.
Gas exchange occurs through the epidermis.
We move by consistently extending and shrinking muscles, pulling us forward and pulling the back section closer to the front.
What I Want in a Mate
I want a mate who:
Can thrive any where I want to go
one that will stay the same gender throughout their lifetime
as young as possible to be prepared for fertilization
