There are many types of nightcrawler worms (also referred to as grunt worms, garden worms, and leaf worms). Earthworms sit in a taxonomic group called annelids, or segmented invertebrates. Most organisms have a mechanism to fix themselves in the substrate. Generally earthworms fall under three categories -- anecic, endogeic and epigeic -- based on their habits. Archaea 7. They can be separated into three major ecological groups based on their feeding and burrowing habits. Earthworms: Earthworms Help The Environment Earthworms are more than just fish bait. They are the main contributors to enriching and improving soil for plants, animals and even humans. Litter dwelling worms, are small (<7 cm) and pigmented, these worms have no permanent homes and prefer to live in the leaf-litter layer of forests. Scientifically, earthworms are classified as Annelids. During the burrowing process, the soil is tilled up and down, allowing oxygen to reach the topsoil layers. The earthworms improve the fertility of soil in different ways and, therefore, they are of utmost importance in agriculture. And although there are more than 4,000 different worm species, all are categorized into three types, anecic, endogeic and epigeic. Protozoa 3.Fungi 4. Algae 5.

Earthworms that are most commonly found in home gardens and farmland are Field Worms (Allolobohora caliginosa) and Night Crawlers (Lumbricus terrestris). Some are harmful to man while others are good for man and environment around. Earthworms create tunnels in the soil by burrowing, which aerates the soil to allow air, water and nutrients to reach deep within the soil. These species do not ingest large amounts of soil.
