I found bunch of red worms coming out of sink. It is rather unusual to find an overwhelmingly large number of worms. It doesn't seem like earthworm or horsehair worm. I don't know much about the worms though.
Could anyone please identify it for me.? Notable features are
- Dark red in color.
- Has a hook like structure at its rear end.
- Moves in both directions front and rear.
- It shrinks when it dwells in water.
