Enchytraeidae Explained

Enchytraeidae is a family of microdrile oligochaetes. They resemble small earthworms and include both terrestrial species known as potworms that live in highly organic terrestrial environments, as well as some that are marine.^[1] The peculiar genus Mesenchytraeus is known as "ice worms", as they spend the majority of their lives within glaciers, only rising to the surface at certain points in the summer.^{[2] [3]} Enchytraeidae also includes the Grindal worm (Enchytraeus buchholzi), which is commercially bred as aquarium fish food.^[4]
