6. Worm Biology Basics The worm used in these two projects is the Red Wiggler or manure worm [Eisensia Foetida] The red wiggler has no teeth, it uses its lip to grasp food. They coat their food with saliva to make it easier to eat. Small stones in the gizzard grind up the food. The food passes through the intestine and comes out as a casting. Worms have no eyes or ears, but can sense vibration or light. They breath through their skin.
