Classification of roundworm from kingdom to species level
What are the classification of roundworm?
Roundworms are divided into two classes, adenophorea and secernenta.
What are the level of classification of nematodes?
Phylum Nematoda is divided into classes. Two of these are class Enoplea and class Chromadorea, each having at least one sub-class. Both classes consist of free-living and parasitic roundworms that live in freshwater, marine water, the soil, or a host.
What are the stages in the life cycle of a roundworm?
With the help of the digestive juices inside the small intestine, the egg cells of the larva dissolve and the embryo hatches out. The larva develops into an adult worm. Adult worms become capable of producing a large number of eggs. They become sexually mature in about 6 to 10 weeks.
How many roundworms species are there?
Not only are there more than 15,000 known species of roundworms, but there are many thousands of individual nematodes in even a single handful of garden soil. And they keep coming! Some species of roundworm may contain more than 27 million eggs at one time and lay more than 200,000 of them in a single day.
What is the scientific name of roundworm?
What are the characteristics of roundworm?
Summary
- Roundworms make up the phylum Nematoda.
- Roundworms have a pseudocoelom and hydrostatic skeleton. Their body is covered with tough cuticle.
- Free-living roundworms are found mainly in freshwater habitats.
- Parasitic roundworms have a variety of hosts, including humans.
How many species are in Nematoda?
Nematode diversity
Despite their invariant body plan, nematodes show an astounding biodiversity. Only around 30,000 species have been described, but the number of extant nematode species is estimated to be a million or more. These species are by no means all alike.
Why are they called roundworms?
Roundworms range in length from less than 1 millimeter to over 7 meters (23 feet) in length. As their name suggests, they have a round body.
What are 3 types of nematodes?
Nematodes that commonly parasitise humans include ascarids (Ascaris), filarias, hookworms, pinworms (Enterobius), and whipworms (Trichuris trichiura). The species Trichinella spiralis, commonly known as the ‘trichina worm’, occurs in rats, pigs, bears, and humans, and is responsible for the disease trichinosis.
How many classes of Nematoda are there?
In a classical morphology-based classification system of the Nematoda there are five sub-classes and nineteen orders; those that contain plant-feeding genera are marked with an asterisk (*).

What are the different types of nematodes?
Roundworms/Lower classifications
What are the two types of nematodes?
The two nematode classes, the Chromadorea and Enoplea, have diverged so long ago, over 550 million years, that it is difficult to accurately know the age of the two lineages of the phylum (Figure 1). Figure 1. Nematodes are multicellular animals in the group Ecdysozoa, or animals that can shed their cuticle.
What are 3 diseases caused by roundworms?
Parasitic Roundworm Diseases
- Ascariasis.
- Hookworm Disease.
- Pinworm Infection.
- Strongyloidiasis.
- Trichinosis.
- Whipworm Disease.
