What are Nematodes? What is Nematode?

Nematoids are a type of worms with a thin linear or cylindrical body, with red or grayish-white bodies, common nematoids, hookworms, and roundworms parasitic on humans.

Generally, it is the child who has the most parasites in the body, and it is usually excreted with the feces.

There is a cavity between the body wall and the digestive canal, which is one of the earliest body cavities in the animal kingdom. This kind of body cavity gives the internal organs of the animal a place to be stored, but there is no body cavity membrane between this body cavity and the muscle layer of the body wall, and there is no orifice to communicate with the outside world, so it is relatively primitive. Most nematodes are non-parasitic and some are parasitic.

It should be a water earthworm.

Water earthworms, also known as red filaria, red nematodes, belong to the aquatic oligochaetes in the annelids, the body color is bright red or blue-gray, slender, generally about 4 cm long, up to 10 cm long. They mostly live in the sludge on the bank of the river basin or at the bottom of the river, dense with the sludge surface, one end is fixed in the sludge, and the other end produces sludge that vibrates in the water, and immediately retracts into the sludge when it encounters alarm. The nutritional value of the earthworm is extremely high, and it should be rinsed repeatedly in clean water before feeding, it is a very favorite bait for goldfish and koi, and it is also the main bait for eel seedlings.

After the tide of the Huangpu River in Shanghai recedes, a large number of earthworms grow in the sludge on the bank, and people catch a large number of them in spring and autumn every year.

Nematodes are the general name of nematodes phylum, their number and species are very rich, there are 35 species found in China at present, among which the more common nematodes are roundworms.

hookworms, whipworms, etc., and most of their body size is cylindrical, and the body color is usually milky white, yellowish or brown, in addition, nematodes have two lifestyles: free and parasitic.

Nematodes are the general name of nematode animals, their number and species are very rich, there are 35 species found in our country at present, among which the more common nematodes are roundworms, hookworms, whipworms, etc., and most of their body sizes are cylindrical, distributed in the ocean, land and other places.

Nematodes have a rich body color, usually milky white, pale yellow or brown, and the size of nematodes varies greatly from species to species, the smallest nematodes are less than a millimeter, but the largest nematodes are up to eight millimeters, in addition, nematodes are mostly dioecious, and the body of the nematodes is generally cylindrical or cylindrical.

Nematodes have two lifestyles: free and parasitic, among which the free-living nematode varieties will go through four molting stages during development, while the parasitic nematodes are divided into two types: plant parasitism and animal parasitism, among which the parasitic nematode varieties in animals have a more complex growth cycle.

Nematodes are prosthetic coelomics, and the phylum Nematode is one of the largest phyla in the animal limb kingdom, with more than 28,000 recorded species, with a large number of species yet to be named. Most of them are small and cylindrical in shape, also known as roundworms.

They can be found everywhere in freshwater, seawater, and land, often surpassing other animals in terms of number of individuals and species, and can be found in extreme environments such as Antarctica and ocean trenches. In addition, there are many species of nematodes that are parasitic (more than 16,000 species) and are pathogens of animals including many plants and humans. Only arthropods are more diverse than nematodes.

The thread-like bugs in the water are thread-splitting fierce bugs. Nematodes live in animals and plants, or live freely in soil, freshwater and marine environments. Nematodes are symmetrical on both sides, long, usually pointed, and have a transparent septum.

Nematodes are less than 1 mm small and up to 8 mm long. The body is usually linear or cylindrical, unsegmented, and symmetrical. <
