EARTHWORMS

Megadrilacea Earthworms are a class of segmented invertebrates that are found in almost every place in the world. Earthworms are typically slender and brown. Most earthworms measure around 4-6 In (12-17 Cm) long, although the Giant Gippsland Earthworm can reach over 6 Ft (2 M) long and 1.5 In (4 Cm) in diameter. All earthworm species live underground in long tunnels. These tunnels are made by the Earthworm pushing its way through the dirt with it's pointed head. When it needs food it comes up to the surface and eats leaves and detritus. But it can't stay out in the open for long. The skin on an Earthworm is extremely sensitive and the sun's rays can dry it out very quickly. The worm (having no eyes) can still detect sunlight however. Cells in the worms skin can sense the sunlight, making it easier for the worm to survive. Worms are also threatened by surface predators such as birds or frogs. The worm most commonly comes out at night or in the rain, but also comes up when it is threatened by predators such as moles or predatory insects. The worm can tell when it is being chased when it feels vibrations in the tunnels, and can tunnel it's way to the surface quickly.

Earthworms are commonly collected and placed into compost piles where scraps of food are disposed of. The worms will help break up the rotting food creating fresh top-soil for gardens.
