Is a worm considered an insect? If not, what is it? Worms are not insects. Insects are in the Phylum Arthropoda, in the class Insecta. All Arthropoda have jointed body parts while Annelids are segmented but not jointed. Earthworms are in the class Oligochaeta (meaning they are segmented worms with only a few bristles). There is a bigger difference worms and Insects than between a Reptile and a Mammal.

Earthworm An earthworm is a tube-shaped, segmented worm found in the phylum Annelida. They are commonly found living in soil, feeding on live and dead organic matter.Its digestive system runs through the length of its body. It conducts respiration through its skin.arthworm is the common name for the largest members of Oligochaeta (which is either a class or a subclass depending on the author).

Annelid A major invertebrate phylum of the animal kingdom, the annelids number more than 9,000 species distributed among three classes: the marine worms (Polychaeta), which are divided into free-moving and sedentary, or tube-dwelling, forms; the earthworms (Oligochaeta); and the leeches (Hirudinea).

Comments: Earthworm vs Leech Earthworms are big segmented worms that belong to the Phylum Annelida, Class Clitellata, and sub class Oligochaeta. Leeches are also worms belonging to the same Phylum and class, but sub class Hirudinae and are of three types, freshwater, terrestrial and marine.

- Marine worms come in a staggering variety of forms. New forms are being discovered all the time and here we can only look at a few selected examples. We begin with the polychaetes (btistle worms). Polychaetes, like the earthworms are segmented (annelid) worms. Earthworms, leeches and some freshwater worms belong to a group called the oligochaetes, since they have only a few spines (chaetae) per segment.

- The nervous system of an earthworm is composed of a primitive brain of fused ganglia, a ventral nerve cord, and peripheral nerves. Impulses from the earthworm s sensory cells are transmitted by the peripheral nerves to certain parts of the body and proper responsive movements are coordinated.

Earthworm The bodies of most oligochaetes (earthworms) are divided externally and internally into well-defined segments. Internally, these segments are divided by membranous partitions. Except for the most anterior and posterior segments, all segments are essentially alike. Earthworms burrow through the soil, feeding on decaying leaves and animal debris. As earthworms move through the soil, they both enrich and loosen the soil. It is for this reason that earthworms are valued by gardeners. An acre of good garden soil may contain as many as 50,000 individuals. External Anatomy and Locomotion of the living earthworm Observe the external features of the earthworm. Notice that the body is made up of a number of segments.

Phylum Annelida A earthworm does not have a skeleton. It has bristles on each segment called setae that help the earthworm move. Earthworms have no limbs. The earthworm has two sets of muscles; one that makes it long and thin and one that makes it fat.t eats dirt, digesting the plant and animal matter in the dirt and then eliminates the rest. It has an esophagus for the food to go down, a crop to store the food in, a gizzard that grinds the food down, intestines for the food to pass through and take out nutrients and an anus for the food to come out.

- The mouth is at the tapering front end, which is usually slightly darker than the rest of the body; the tail end tends to be more flattened than the head and lighter in color. Its reddish tinge is due to the oxygen-carrying pigment hemoglobin in the blood. The earthworm's body is made up of segments. On each segment, except the first and last, are four pairs of tiny bristles called setae that help the worm move through the earth. It also has five pairs of hearts in the front of its body. The hearts help circulate the worm's blood.

Earthworms & Soil Formation Earthworms are important members of the soil food web, a complex community of organisms that impact the process of soil formation. The soil food web consists of soil-dwelling organisms, ranging from bacteria, algae and fungi to insects, small mammals, reptiles and plants.

- The digestive system is divided into the buccal cavity (mouth), pharynx, esophagus, crop, gizzard, and intestine. While not having a true brain, earthworms have a ventral nerve cord that runs the length of the worm, a network of nerves that control the muscles, and various photo, chemo, and tactile receptors.

- The annelids (Phylum Annelida) are also called the segmented worms due to their segmented bodies. This group includes the most familiar of all invertebrate worms. Earthworms, freshwater worms, leeches, and marine worms are all annelids.This group is also called bristle worms because most annelids have tiny chitinous bristles called setae. The setae help terrestrial annelids grip their surroundings, and they aid aquatic forms with swimming.earn more about this article. Annelida is a group commonly referred to as segmented worms, and they are found worldwide from the deepest marine sediments to the soils in our city parks and yards.

Worm Classification Several different species of worms are included in each group, but all have some similar qualities. The following are the three classifications: Annelida – This group is probably the most recognized of the three worm classifications. Phylum Annelida includes some sea worms, but it is mostly comprised of segmented worms such as earthworms. Earthworms are also an unofficial broad classification of worms. Hundreds of different worm species in 16 families are considered earthworms. Earthworms are also divided into three subcategories depending on their ecosystem.

- (assorted species, including: Lumbricus terrestris and Lumbricus rubellus). The two most common species of earthworms in Northern Virginia are the Common Earthworm, or nightcrawler (Lumbricus terrestris) and the Red Earthworm (Lumbricus rubellus).These earthworms were introduced from Europe many years ago.arthworms are hermaphroditic, meaning they can all lay eggs after they mate. Earthworms lay coccoons which have an egg inside. Once an earthworm has hatched, it can live up to about three years. Earthworms are hermaphroditic, meaning they can all lay eggs after they mate.
