Worm Quizzes Online & Trivia

Earthworms are an example of segmented worms. The annelids, also known as the ringed worms or segmented worms, are a large phylum, with over 17,000 extant species including ragworms, earthworms, and leeches. The species exist in and have adapted to various ecologies – some in marine environments as distinct as tidal zones and hydrothermal vents, others in fresh water, and yet others in moist terrestrial environments. The annelids are bilaterally symmetrical, triploblastic, coelomate, invertebrate organisms. They also have parapodia for locomotion. Although many species can reproduce asexually and use similar mechanisms to regenerate after severe injuries, sexual reproduction is the normal method in species whose reproduction has been studied.

1. Pieces of malicious code that make copies of themselves and spread through computers without human interaction. In the case of computers, a worm is a piece of code that usually invades your computer through upatched software and replicates itself until it reaches the internet and spreads there as well.

Worms reproduce both asexually and sexually. Asexual reproduction is a type of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only; it does not involve the fusion of gametes, and almost never changes the number of chromosomes. Asexual reproduction is the primary form of reproduction for single-celled organisms such as the Archaea and bacteria. Many plants and fungi reproduce asexually as well. Sexual reproduction is a form of reproduction where two morphologically distinct types of specialized reproductive cells called gametes fuse together, involving a female's large ovum (or egg) and a male's smaller sperm. Each gamete contains half the number of chromosomes of normal cells.

Flatworms are worms that have a soft body and no backbone. They are found in the kingdom known as animalia and the phylum called platyhelminthes. They have a bilateral symmetry and three main cell layers. They also have a distinct brain and specialized digestive system. They also have a specialized excretory system which means that these systems are not simple. They do not have body cavities containing internal organs and they do not have specialized circulatory and respiratory organs. There are common examples of flatworms found around the world. One type is called the tapeworm. Sometimes, the tapeworm can get into a person’s or animals’ system. This can cause problems for the person or animal and make them very sick.

There may be different worms that are available in this world but there are five characteristics that they all share with each other. The presence of all these characteristics will make it clear to you that you are dealing with worms: They do not have legs; They are all invertebrates; They have bilateral symmetry; They have long and narrow bodies; They have heads and tail ends. Worms are very effective in breaking down organic matter. They can create natural fertilizers that will improve the condition of your soil. A lot of worms are known to be good for plants. There are some speculations that worms can be eaten and while they are known to be good for the body, other people would rather not try it.

Trichostrongylus is important in stronylidae because of food animals. Trichostrongylus species are nematodes (round worms), which are ubiquitous among herbivores worldwide, including cattle, sheep, donkeys, goats, deer, and rabbits. At least 10 Trichostrongylus species have been associated with human infections. Infections occur via ingestion of infective larvae from contaminated vegetables or water. Epidemiological studies indicate a worldwide distribution of Trichostrongylus infections in humans, with the highest prevalence rates observed in individuals from regions with poor sanitary conditions, in rural areas, or who are farmers / herders. Human infections are most prevalent in the Middle East and Asia, with a worldwide estimated prevalence of 5.5 million people.

The three phyla of worms are flatworms, segmented worms and roundworms. Worms are many different distantly related animals that typically have a long cylindrical tube-like body and no limbs. Worms vary in size from microscopic to over 1 metre (3.3 ft) in length for marine polychaete worms (bristle worms),[1] 6.7 metres (22 ft) for the African giant earthworm, Microchaetus, and 58 metres (190 ft) for the marine nemertean worm (bootlace worm), Lineus longissimus. Various types of worm occupy a small variety of parasitic niches, living inside the bodies of other animals. Worms can be divided into several groups, but are still technically decomposers.

The common name for Haemonchus is large stomach worm and barber pole worm. Haemonchus contortus, also known as the barber's pole worm, is very common parasite and one of the most pathogenic nematodes of ruminants. Adult worms attach to abomasal mucosa and feed on the blood. This parasite is responsible for anemia, oedema, and death of infected sheep and goats, mainly during summer in warm, humid climates. Females may lay over 10,000 eggs a day, which pass from the host animal in the faeces. After hatching from their eggs, H. contortus larvae molt several times, resulting in an L3 form that is infectious for the animals. The host ingests these larvae when grazing.

The common name for Dirofilaria immitis is heart worm. Dirofilaria immitis, the heartworm or dog heartworm, is a parasitic roundworm that is spread from host to host through the bites of mosquitoes. The heartworm is a type of filarial worm, a small thread-like worm that causes filariasis. The definitive host is the dog, but it can also infect cats, wolves, coyotes, jackals, foxes, and other animals, such as ferrets, bears, sea lions and even, under very rare circumstances, humans. The parasite is commonly called "heartworm"; however, adults often reside in the pulmonary arterial system (lung arteries), as well as the heart, and a major effect on the health for the animal is a manifestation of damage to the lung vessels and tissues.

The common name for capillaria plica is bladder worm. Capillaria plica is a parasitic nematode which is most often found in the urinary bladder, and occasionally in the kidneys, of dogs and foxes. It has also been found in the domestic cat, and various wild mammals. Its presence usually produces no clinical symptoms, but in some cases, it leads to hematuria (blood in the urine), cystitis (inflammation of the urinary bladder), or difficulty in urination. Prevalence rates of up to 50% in wild hosts and 76% in kennel dogs have been reported. Most infected animals exhibit no clinical symptoms.

The common name for Aelurostrongylus abstrusus is cat lung worm. This worm was originally found and described by Mueller as Strongyluspusillus. In 1898, Railliet changed the name to Strongylusabstrusus. Braun and Luehe described a species from the cat that they named Strongylusnanus. In 1907, Railliet and Henry erected the genus Sythetocaulus to include this worm. Cameron erected the genus Aelurostrongylus and concluded that the larva passed in the feces was capable of infecting mice; this work has never been duplicated. This is a metastrongyloid nematode parasite of the cat around the world. The adults live in the terminal respiratory bronchioles and alveolar ducts.

The common name for ostertagia is brown stomach worm. Ostertagia ostertagi, commonly known as the medium or brown stomach worm, is an important parasitic nematode (round worm) of cattle. O. ostertagi can also be found to a lesser extent in sheep, goats, wild ruminants and horses. The species causes ostertagiosis, which is potentially fatal in cattle. It is found worldwide and is economically important to cattle industries, particularly those found in temperate climates. O. ostertagi has a direct life cycle, which consists of two stages: the free-living stage on pasture (pre-parasitic) and the parasitic stage in the host (e.g. cattle).
