They are known under different names like tiger worms, red worms, red wigglers… They are composting worms for use in worm farms. PHARYNX: Pushes food down into the digestive system.ĬEREBRAL GANGLION: Nerves that serve the brain.ĮSOPHAGUS: Connects the pharynx with the crop.īLOOD VESSELS – DORSAL AND VENTRAL: These are like tubes that carry blood to the front and back of the worm.īRISTLES OR SETAE: Tiny hairs all over the body that help the worm feel around and get where they need to go.We sell Eisenia Fetida in 250g portions with appropriate bedding. I like to use raisins to simulate! YEP!!! There are more areas you could add but I like to keep it simple. This is where the worm castings exit the worm. INTESTINES, AGAIN: Make another cavity toward the end that shows another view of the intestines that stretch through the worm. This is where the adult worm releases the cocoons through a stream of mucuos. Fold foam like an accordion to depict intestines.ĬOCOON MAKER (Clittelum): Fold a strip of the plastic tablecloth and wrap it around a few times to widen this section.
INTESTINES: This would be the third cavity right before the “cocoon maker”, the thick area in the middle. It uses gritty stuff fro the soil to smash up the materials. GIZZARD: This part of the worm helps grind up the food. REPRODUCTIVE ORGANS: Add some other shapes to represent two organs.ĬROP: This is where the food is held before it gets ground into mus, somewhat like a stomach. Cut foam hearts out and glue inside the first main cavity.
HEARTS (aortic arches): A red wiggler has 5 “hearts”. It’s a tiny mouth that operates like an elephant’s trunk and is technically named the same, a proboscis. MOUTH (proboscis): Make a hole in the front so you can simulate how food will be eaten. Parts of the Red Worm Model (Eisenia fetida) Sheets of craft foam made for some interesting guts. Once I pressed all the plastic down I cut out areas to show the insides. Then I sprayed adhesive over the entire noodle and wrapped it in one layer of red plastic (cheap tablecloth). I made this model out of a pool noodle! First I scored rings along the entire worm with a serrated knife to resemble segments. It’s fun to show children how a red wiggler works. When I bring worms in to school, they quickly captivate even the most squeamish. I’ve given away more than 20 worm bins to kids and adults. I started many years ago and have brought them with me when I moved. I love composting with red wiggler worms.
