There are literally thousands of different types of worms on the earth. Some can be found in just about any garden or backyard, while others may be found buried beneath the sand on hundreds of beaches overseas. Whether they live in the dirt or sand, most worms belong to the segmented worms group. There are more than 9,000 species of segmented worms in existence today such as sandworms, leeches, and earthworms, to name just a few. Segmented worms (phylum Annelida) have elongated, cylindrical bodies that are segmented or divided by grooves, both internally and externally.
The earthworm is the largest and most varied group of segmented worms in the world. Just think, there are more than 2,700 different types or earthworm living in every corner of the earth today. Earthworms can be found in just about every corner of the earth. They live in trees, in bark, and under rocks as well as along rivers and near springs, and ponds. Their favorite place to live, however, is in the earth’s rich soil. During the winter months they burrow deep within the earth until the surface warms again during the spring. During the warm summer months, worms stay closer to the tops of soil where they create tunnels to wiggle in and out of. These tunnels are extremely important for plant life as they create a path for water and air, which is essential for the survival of plant life.

Places like China, Australia, Greenland, and the Sahara Desert have their own indigenous species of worms. Besides the Sahara Desert, you won’t find large numbers of worms living in “sandy” areas, especially sandy beaches. The vast majority of worms on our planet can only survive under certain environmental conditions.
Worms have no lungs, so they breathe through their skin. This means that the worm’s environment and skin must be moist at all times. This allows the worm to breathe in oxygen. If the worm’s skin dries out, the worm will die from suffocation. While worms need moisture to survive, too much moisture can be fatal. If too much water is present, it takes the place of oxygen, which will cause the worms to flee to the surface. Once on the surface, worms will be exposed to sunlight. If worms remain in the sunlight for too long, they can become paralyzed.
In addition to needing a moist environment for survival, worms must also remain close to their food supply. Worms feed off of leaves and dead grass, which contain organisms that provide a healthy diet of bacteria, algae, and fungi. Worms feast on dirt as well, especially if they live deeper inside the earth. Worms also eat plants, fruits and vegetables.

Although you cannot see them, believe it or not, worms do have mouths. The worm’s mouth is actually big enough and powerful enough to grab a leaf and drag it around. They also have a pharynx, esophagus, crop, gizzard and intestine. When the worm eats its food, it pulls the materials into its mouth with the help of the pharynx and its prostomium (also called acron). This creates a suction motion. This suction motion aids in helping the worm consume large amounts of food in a sort amount of time. The gizzard grinds the food. Worms eat so much that they typically produce excrement equal to their own weight every 24 hours.
The worm’s moist, sustenance rich environment plays an extremely important role in reproduction as well. Worms prefer to mate and reproduce in warm moist soil, away from the light.
