Worms

Worms are a group of invertebrate zoology characterized by the presence of a coelomic sac inside the body in the form of a coelomia and a rather flexible way of attaching the intestines to the nervous system. This group of protorotata is characterized by the presence of more than 2 coelomic sacs (latent coelomia), which are interconnected by a gap. All members of the worm group can live as free-living organisms or attached to something. More than one of the two types of coelomia must be opened to convert the neoceracindrum into a fascial cavity that makes room for the spine (myotomy).

All representatives of the protostomes subphylum have a proto-, nemato-, or sporozoite mode of reproduction. The process is nematic

Worms are a group of animals with elongated bodies. They are representatives of invertebrates, i.e. they lack an internal skeleton. This type of animal is the only one that has an elongated body. Usually the body shape is that of a worm. But there are worms in the form of starfish and even coils. Worms can be small or huge. There are also those that occupy territory, like vipers or ants. Their body has a smooth mucous membrane. Worms do not have legs or paws, but they have a special muscular system that allows them to move along the ground. The main source of food for them is the cells of dead animals and plants.

In general, the name “worms” is very outdated and stylistically inaccurate. It only tells us that they can be found in the ground or placed in this soil. Why not use a more modern designation for this group of animals? In biology they use the term "nematodes". After all, this is the name of the genus of animals, which includes a large number of species of similar worms.

If we are talking specifically about parasitic worms, then they are not at all a subtype of gastropods (as some types of worms were previously called). After all, they themselves are permanent residents of their host’s body. That is why they use a separate category of organisms - ankylosoa and dragomolisoa. This includes species of worms that are viviparous and have a free lifestyle. But usually they talk about parasites and compare them with animals from this group.

Worms are a primarily oral type of invertebrate animal, which is characterized by an elongated and multi-segmented body. Many types of worms parasitize humans and animals and are potential carriers of diseases. In this article, we will take a closer look at the biological characteristics of worms, their life cycle, and control options for different types of worms.

Structure and life cycles of worms There are many types of worms, which differ from each other in body structure, shape and size. Some types of worms have long bodies, reaching several meters, while others are short and only a few millimeters in diameter. They also vary in the degree of activity, some types are active worms, and some are passive. Some types of worms are not only parasites of humans and animals, but can also provide benefits to the ecosystem. For example, some species of earthworms recycle organic matter into the soil, which contributes to soil fertility. However, most types of worms are still dangerous parasitic organisms. Classification of celiac worms by type of parasitism Worms are also divided into two main groups: free-living and parasitic. Free-living worms live in water, soil or on plants, while parasitic worms live inside the body of another animal - the host. The main difference between parasitic worms and free-living ones is that the latter feed
