Red Wiggler worms start out as cocoons (contains about 4 to 6 baby worms only), and begin with the Egg stage. Mature Stage The 2nd stage is when a juvenile red wiggler worm or Eisenia foetida turns into an adult. A mature red wiggler can be expected to live between one to three years. The oxidative damage to DNA prolonged cell cycle arrest at the G2/M-phase transition in mitosis, thus stimulating and accelerating apoptosis in earthworm intestine. Seventeen metals were analysed in E. fetida tissue, bulk soil and soil solution. Add to it the fact that these worms have an average lifespan of 3 to 4 years, and the rapid rise in their numbers makes perfect sense. Both "forms" have a mean length of 60-120 mm, a diameter of 3-6 mm and a segment number varying between 80 and 120. Share this item.
