Ill take the camera out there next time.

I have some weird species of earthworms in my yard that are snow white. If I'm digging and accidentally cut one apart his(or her) little guts look like milk. They don't glow, but they are pure white. These worms live mostly around my pecan trees. Cheryl

African nightcrawlers have a purpleish sheen that looks irredesent in good light. They usually live under leaves and ground clutter and jump around a lot when handled. They have a flat bottom also.
