These are either red wigglers (Eisenia fetida) or red worms (Lumbricus rubellus).
They're classified as epigeic worms, defined as those who live near the surface of the earth. Nightcrawlers (Lumbricus terrestria) are anecic, meaning they live deep in the ground. And then there are endogeic worms, which live in the roots of plants.
