Silkworms make silk by spewing a substance called fibroin through small holes in their jaws called spinnerets. The spewed-out substance consists of digested leaves and protein produced by the worm. The silkworm produces up to 1200 silken threads within a 72 hour time period, creating a soft, silver cocoon. Once the cocoon process is complete, silk farmers harvest the threads with steam, and the delicate fibers are spun and woven into silk fabrics.Know More
Silkworms use their salivary glands to produce fibroin, and they create their cocoons by rotating repeatedly for up to 72 hours. Each cocoon produces approximately one kilometer of silk fiber. Silk farmers remove the cocoon with steaming water and carefully unwind the cocoon fibers.
Silkworm farmers harvest silkworm eggs by incubating them until they hatch into caterpillars. The larvae are fed mulberry leaves and lettuce for approximately six weeks. While silkworms feed on a variety of plant life, their favorite meal is mulberry leaves. Silkworm larvae that is fed only mulberry leaves during the feeding process are known to produce the finest silk on the market. During this time, the silkworm eats 50,000 times its weight in plant materials. Once the silkworm reaches a maximum weight and height, it changes color and prepares to spin its cocoon.Learn more about Worms

An earthworm's food is consumed, stored and broken down inside its digestive tube, which starts at the mouth and ends at the anus. Along the way, ingested soil is ground down to finer particles, allowing blood vessels in the intestine to absorb nutrient-rich organic matter.Full Answer >
Glow worms produce light using a chemical reaction involving the chemicals luciferin, luciferase, ATP and oxygen. They use this light primarily to attract mates, but also to ward off predators. Glow worms have powerful bitter-tasting compounds in their bodies that predators learn to associate with their glow.Full Answer >
Earthworms reproduce through a unique copulation process whereby two worms line up against each other and excrete a type of mucous that forms a layer that encapsulate their bodies. Both worms release sperm into the mucous. After various other processes are completed, the sperm reaches the sperm receptacles on the opposite worm.Full Answer >
