The difference between red worms and earthworms

The red worm, Chironomus larva, is one of the main groups of zoobenthos in freshwater waters. Earthworm is a general term for annelid oligochaeta, a common terrestrial annelid. At present, there are more than 2500 species of earthworms, which are called the most valuable animals on earth by biologist Darwin. Let's take a look at the difference between red worms and earthworms.

The difference of families and genera between red insects and earthworms

1. Red worms: red insects are the larvae of the animal kingdom, phylum Arthropoda, subphylum jaws, Insecta, Diptera, Chironomidae and Chironomidae.

2. Earthworms: earthworms are the general name of animal kingdom, annelid phylum, banding class, oligohair subclass, unidirectional earthworm order, unidirectional earthworm suborder and annelid.

Morphological differences between red worms and earthworms

1. Red worm: red worm cylindrical worm-shaped, slender body, a total length of 2-30 mm. It is composed of head shell and 12 body segments. the first 3 body segments are sternal segments and the last 9 body segments are ventral segments. The thickness of each segment is similar, and there is no difference in appearance. The body color is light, and some species are blood red due to the presence of heme in body fluids.

2. Earthworms: earthworms are cylindrical, symmetrical and segmented, and are composed of more than 100 body segments. after the eleventh section, there is a dorsal hole in the center of the back of each section, there is no bone, and it belongs to invertebrates. The surface of the body is covered with a thin layer of horny layer with pigment, and all segments have bristles except the first two segments of the body.

The difference of feeding habits between red worms and earthworms

1. Red worms: most red worms feed on organic matter in water. In silt or water bodies rich in organic matter, they can reproduce in large numbers due to the lack of natural enemies such as fish and shrimp. Except for some specializing plant species in Chironomus, the other species can be divided into carnivorous and omnivorous species. Carnivorous species feed on crustaceans, oligophairs and other Chironomus larvae. Omnivorous species feed on bacteria, algae, aquatic plants and small animals.

2. Earthworms: earthworms can secrete a special enzyme that can decompose protein, fat and lignocellulosis. leaves, rice straw, livestock and poultry manure, domestic waste, activated sludge and scraps of paper and food industry can be its food. can eliminate environmental pollution to a certain extent.

The difference between the function of red worm and earthworm

1. Red worm: red worm plays a significant role in accelerating organic mineralization and eliminating organic pollution in water material cycle, and is widely used in the field of ecology and environmental science, and it is also an excellent natural bait for fish. it has high nutritional value, so it is closely related to fishery.

2. Earthworms: earthworm traditional Chinese medicine is called earthworm, which is cold and salty, with functions of clearing heat, relieving spasm, relieving asthma, diuresis, mainly treating high fever, mania, convulsion, headache and eye deficit, wheezing phlegm-heat, stroke, hemiplegia and other syndromes. Traditional Chinese medicine is commonly used in the treatment of diseases such as prostate and other diseases such as damp-heat injection of urinary tract infection, providing fluid has a good effect of relieving cough and asthma, and the mixture of ash and rose oil can treat baldness.
