1: The secret life of the worm
2: We are all worms. But I believe that i am a glow-worm. -Winston Churchill
3: Habitat: Worms live near or at the surface of the earth. They live in damp soils of regions having moderate or warm climates.
4: Adaptations: In all animals, types of adaptations can be grouped into three main categories: structural, physiological. and behavioral.
5: Structural: The physical adaptations of the organism include setae on each segment of the earthworm's body, and a streamlined body to burrow, circular and longitudinal muscles, and being able to push its pharynx out of its mouth to grasp hold of its food.
6: Physiological Adaptations: Earthworms secrete a mucus that helps them move more easily through the soil, glow in the dark, and kill bacteria in the soil.
7: Behavioral Adaptations: Earthworms are sensitive to vibrations, spend their days under ground due to light sensitivity, lose moisture through their skin, therefore they come out when ground is wet.
8: Life Style: The earthworm has no eyes, but they can tell when they are in the light or the dark. They have no ears, but their bodies can sense vibrations. Worms have a brain, nerves, and muscles. They can even detect some tastes. Worms breathe in air and carbon dioxide out, but they don't have lungs.
9: Continued: They can't breathe through their mouth, and they can't breath through their nose (they don't even have one!), so they breathe through their skin. They have muscular mouths, and can pull leaves into their burrows. Worms have five hearts.
10: What they eat: Worms on the surface, or close to it, eat a variety of organic materials such as dead grass, leaves, and algae. Worms that live deeper underground have a diet of primarily raw dirt. The worms eat the bacteria, fungi, and bacteria living in the dirt.
11: Extra Information: Earthworms are soft bodied animals. Their bodies are divided into a number of similar rings. Their head tapers to a point. Their tail is broad and flat.
