The Origins of the Phylum Neematoma



PHYLUM NEMATOMORPHA or commonly known as white lace-worm is a parasite that usually infects horses. The scientific name of this parasitic worm is Cynodemia Spinosa or simply C. Spinosa. It is usually acquired from contaminated soil, water, or any other organisms present in the environment. The name PHYLUM NEMATOMORPHA is very appropriate since this type of worm has an important role in the ecosystem. The name comes from the fact that the adult worms are white in color, while the larvae are black or gray in color. The word “nematomorph” is derived from the word” Nematode”, which means “worms”.

Arthropods is divided into two subclasses

This class of aquatic arthropods is divided into two subclasses: phylum Nematoda and phylum mollusk. Worms in the phylum Nematoda are classified as true parasites (i.e. ectoparasites) since they infect only marine animals and birds, whereas those in the phylum mollusk are true ectoparasites that infect both land and aquatic animals. In addition, there are three subclasses of these nematomorphs: land-parasite, epidermatophytic philate, and parasitic amoeba.


The primary prey of phylumonasan arthropods are mostly crustaceans such as hermit crabs, slugs, snails, and other terrestrial arthropods. The eggs of these parasites are also eaten by some arthropods such as ground beetles and slugs. They also serve as intermediate hosts for arthropods that feed on the roots of trees and plants. There are two types of Alternaria – marine and terrestrial. The marine type can infect either marine animals or terrestrial arthropods such as gordians.

Prey of the phylum nematomorpha

The most common prey of the phylum nematomorpha is grasshoppers and their larvae. Although it is called a grasshopper, it is actually a type of cicada. Cicadas are arthropods that usually feed on dead tissues. The larvae of these cicadas are called horsehair worms. These are some types of nematodes that have long bodies and antennae. It has a yellowish color and its entire body is covered with a grayish-colored tape-like exoskeleton.

Reproductive organs

The reproductive organs of these cicadas are very different from the cuticle of the nematodes. The siphonophorete organ of the horsehair worms is present at the end of the siphodium. In comparison to other nematodes, this type of cicada does not bear any prothallium or cast layer.


The appearance of the PHYLUM NEMATOMORPHA is very distinct. Its head is much shorter than its body and it has a grayish colored band that separates it from the body. The grayish color of its band indicates that the animal is fed once every two weeks. It also has small ears, large black tongue, head with a white stripe along with a dark grayish color on the undersides of its legs.


This cicada has some distinct physical features compared to other species of the phylum nematomorpha. Its body is very robust with a short and robust tail. Its long legs and powerful jaws help it in capturing food. Its large and strong forelimb helps it in walking on surfaces. Its pair of longitudinal muscles help in walking and leaping.


This is a contain clade and it was named after Sir Bernard Shaw, a famous naturalist and his description of these animals was the first basis for this taxonomic grouping. These are also known as common snails or common corals. These are found in temperate to tropical waters all over the world. There are approximately 4000 described species in this family. Most are found in fresh water and some are found in saltwater. Approximately half are known from fossil material.


It is one of two cicada clades that are distributed broadly in the Old World (amins). The other is known as the distinctly marine cicada (Persian gray cicada). These animals are not marine, but they do inhabit freshwater. They feed on organic waste, which includes dead fish and other forms of plankton. Some, however, do make seeps into freshwater to seek food along their migration paths, as is the case for the common snails.


During the early stages of development, the common snails resemble those of the land mollusks. Their external shape resembles that of a teardrop. At that stage, the animals’ color becomes reddish-brown or black. The external hard surface (the prothallium) eventually hardens into the shell lining, and new translucent polyps form across the opening.


After these changes have occurred, an arthropod host migrates to the hypopharynx to feed. As it does so, the hypopharynx starts to develop into the first segment of the digestive tract. This segment contains the hypopharynx, tongue, base of the tongue, and finally the colon. When the food reaches this area, it reaches the large bowel through the cloaca. Then, the entire process begins over again.
