Wait ten minutes than start pulling the castings away from each pile, causing the worms to retreat to the center to avoid light. Repeating this process will result in a ring of castings surrounding a pile of worms, which can be returned to the bin along with new bedding to begin the vermicomposting process over again. Each worm has five pairs of hearts and a simple brain. The average worm is made up of 100 to 200 ringed segments. A worm can grow a new head or tail if some of its segments are nipped off.
Worms have no teeth or eyes but have highly sensitive skin.
Worms breath through their skin. A worm can eat about half its own weight in food scraps every day. An enlarged cummerbund-like band near the worm's head holds the reproductive organs. Eight breeding worms can become 1,500 worms in 6 months. Each healthy worm may produce an egg capsule every 7 to 10 days.
