Which order do earthworms belong to?

The question of which order earthworms belong to can easily be answered

To classify certain animal species, scientists divided the animal world into different tribes, classes, orders, and families. So that you can answer the question of which order earthworms belong to, assume external characteristics in order to assign them to a group.

• The external characteristics of animals include, for example, the presence of legs, eyes and mouth. Examine whether there is any skeleton or hair. You should also pay attention to the shape of the body.
• On the basis of the characteristics you can now understand that the family of earthworms belongs to the tribe of annelid worms, to the class of belt worms and to the order of the few-bristles.

Describe earthworms from the tribe of annelids

• If you take a closer look at an earthworm, you will notice that it has thin, slimy skin. For him, strong sunlight and drought are fatal, so that he mostly stays in the ground and thus belongs to the humid-air animals.
• On the surface, you don't see the worm's front, back, or limbs. On closer inspection, however, you will notice up to 150 body rings, which you also call segments and are among the most striking features. This explains which tribe earthworms belong to - the ringworms.


What do earthworms eat?

Earthworms are hard-working little helpers in your garden. Everything they eat and ...

• The segments include a lobed, protruding segment at one end of the body. They call it the head rag that covers the mouth opening. You can recognize the anus at the other end, as it is flattened and pointed.
• In each of the segments between the head and anus, only four pairs of chitin bristles are embedded, which support the locomotion. This explains why you find the worm in the low-bristle order. On closer inspection, they also notice a lightly discolored thickening in the front third of the body, called the belt, which plays a major role in reproduction.
• Earthworms have two muscle layers that are fused with the epidermis to form the skin muscle tube. This allows you to observe undulating movements in a crawling animal. If the inner longitudinal muscle layer contracts, the body of the worm becomes shorter and thicker; if the outer circular muscle layer contracts, it becomes long and thin.
• The locomotion is supported by the chitin bristles, which can be anchored in the ground or on other surfaces and thus prevent slipping back. It is interesting for you to know that the animal can also climb up and down in its burrows.
