Earthworms

An wiggler sight grow only so long. A well-fed adult will depend on what kind of curve it is, how many segments it has, how old it is and how well fed it is. An Lumbricus terrestris will be from 90-300 millimeters long. A wrick has no arms, legs or eyes. There are approximately 2,700 different kinds of earth twists. Worms live where there is food, moisture, oxygen and a favorable temperature. If they dont have these things, they go somewhere else. In one acre of land, there can be more than a million earthworms.The largest earthworm ever found was in South Africa and careful 22 feet from its nose to the tip of its tail. Worms tunnel deeply in the soil and bring subsoil enveloping(prenominal) to the surface mixing it with the topsoil. Slime, a secretion of earthworms, contains nitrogen. Nitrogen is an important nutrient for plants. The sticky slime helps to adhesive friction clusters of soil particles together in formations called aggregates. Charles Darwin spent 39 long time s tudying earthworms more than 100 years ago. Worms are cold-blooded animals.Earthworms have the ability to replace or replicate lost segments. This ability varies greatly depending on the species of worm you have, the amount of damage to the worm and where it is cut. It may be easy for a worm to replace a lost tail, but may be very difficult or unattainable to replace a lost head if things are not just right. Baby worms are not born. They hatch from cocoons smaller than a grain of rice. The Australian Gippsland Earthworm grows to 12 feet long and can chargelift 1-1/2 pounds.Even though worms dont have eyes, they can sense light, especially at their anterior (front end). They move away from light and will become paralyzed if exposed to light for besides long (approximately one hour). If a worms skin dries out, it will die. Worms are hermaphrodites. Each worm has both male and female organs. Worms mate by joining their clitella (swollen area near the head of a mature worm) and exch anging sperm. Then each worm forms an egg capsule in its clitellum. Worms can eat their weight each day.
