For example, what kind of animal is a centipede swimming in the water with many legs?

Water centipedes and mussel shell insects (also known as mussel shrimp) are aquatic pests that seriously harm fish fry. In the process of rearing fry, if as follows.

The methods can effectively prevent and control the harm of water centipedes and mussels to fish fry.

1. Water centipede harm and prevention.

1.Hazards and symptoms.

Water centipedes are also known as water clips. Water centipede is the larvae of dragon lice, and the larvae of dragon lice and dragon lice are common in ponds, which are more harmful to fish fry. The water centipede has a cylindrical body shape with a pair of pincer-like jaws, much like the centipede's poisonous claws, hence its name.

The larvae are grayish-white, molt and grow, about 3 cm long, and often breathe with their tails exposed to the water. The water centipede is a very ferocious and voracious aquatic pest, often sucking its body fluids by pinching the fry to death with its large jaws. However, the water centipede is not harmful to the summer flower fish species above 3 cm.

2.Diagnosis and prevention.

In ponds where water centipedes are seriously harmed, careful observation can often see water centipedes chasing and biting fish fry, and water centipedes can also be seen swimming stupidly in the water, waiting for an opportunity to harm them. The following methods can be used to prevent and control: first, pre-stocking control, that is, before stocking, the fish fry pond is thoroughly cleaned with quicklime once, which can effectively kill the water centipedes and larvae in the water; The second is the prevention and control of feeding, that is, the fry should pay attention to the prevention and control of water centipede hazards in the process of breeding and breeding.

2. Hazards and prevention of mussel insects.

1.Hazards and symptoms.

Mussels belong to the order Crustacea Mesomorpha. It often grows in the water body with shallow cement bottom, which can cause a large number of fish fry to die, and six kinds of aquatic mussel shrimp pests that harm fish fry have been found in China, such as round mussel shrimp and narrow mussel shrimp. Studies have shown that mussel shrimp are dioecious.

The body shape of the round mussel shrimp is like a small mussel, approximately round, the shell is millimeters long, millimeters high, translucent, the shell mask has 6 concentric circles and 7 growth lines, and the shell glands are large and clear. The narrow mussel shrimp is slightly larger than the round mussel shrimp, which is oblong and oval, with a shell length of millimeters and a height of millimeters, and has 17 concentric circles and growth lines. When the mussel shrimp appears in large quantities in the pond, it can make the water tumble and change color, and the juvenile fish can not only live and feed normally, but also the mussel shrimp will consume a large amount of dissolved oxygen in the water, and sometimes it can also cause the phenomenon of flooding the pond.

In addition, because mussels and shrimp seize nutrients from the water, they can cause the growth of fish fry to grow slowly due to insufficient nutrition, and even cause a large number of fish fry to die.

2.Diagnosis and prevention.

When a large number of juvenile fish are found to be dead, if the water color of the pond changes greatly, in addition to using a mirror to check whether the fish are attacked by pathogens, a small amount of pond bottom water can also be taken to settle down, and then samples are taken to observe under a dissecting microscope to check whether there are a large number of mussels and shrimp.

Water centipede, there are many kinds of names, Yunnan is called the crown insect, there are more rivers with turbulent water, mostly in the stone underground, generally the river is diverted to expose the riverbed and turn over the stones to scratch, the big ones are sold by the strip, generally one yuan, and the restaurant sells higher. They are all fried and eaten, and when eating, they should be rubbed with salt several times to wash the dirt on the surface. The nutritional value is very high, and it is high in protein.

What is said on the 2nd floor should not be called (water centipede) Water centipede is a kind of plant medicine Sent from the 3rd floor** It was said on the 1st floor (dragonfly larvae) I was speechless.

The centipede's body is composed of many body segments, each of which has a long foot, so it is a multipoped creature. Centipede, also known as Tianlong, centipede, less-spiny centipede, Wu Gong, maggot, etc., is a venomous, predatory terrestrial arthropod.

There are three common centipedes: red-headed, green-headed, and black-headed. The back of the red head is reddish-black, the belly is pale red, and the feet are pale orange-red or yellow. The green head has a blue back and feet, a pale blue belly, and is small in size, about half the length of the red-headed centipede.

Captive-bred:

The lifespan of centipedes is only 6 years, and after sexual maturity, they generally mate in the early morning after the rain in March, May and July, and begin to lay eggs in 40 days, and the female centipede produces fertilized eggs on her back in order to hatch in time.

Each female centipede ovulates for 2 3 hours at a time, laying 30 60 eggs each time. The surface of the egg is rich in mucus, and the egg grains stick together to form an egg mass. During hatching, the female centipede does not eat or drink until the young centipede hatches, and then grows to adulthood.

Centipedes are typical carnivores, with a wide range of eating habits, especially like to eat a variety of insects, such as mealworms, crickets, beetles, termites, cicadas, dragonflies, spiders, flies, bees and their eggs, pupa, larvae, etc.

At the same time, it also eats meat, offal, blood, cartilage, etc., fruit peels, potatoes, carrots, tender vegetables, etc., milk, bread, etc., which can also be used as food for centipedes.

Many legs resemble centipedes are grasshoppers, also known as money strings. The grasshopper is a centipede of the genus Cervid, with a yellowish-gray body color and a body length of about 25-50 mm, and its most distinctive feature is that it has fifteen pairs of very long and fragile feet. So what are the things with many legs like centipedes, and what else is there, you can continue to understand as I continue.

1. Worms and centipedes are very similar in shape, they are also multipopeds, the number of feet of worms is generally 15 pairs, and the number of centipede feet will vary depending on the species.

2. The worm belongs to a kind of arthropod, which is mainly composed of six parts: the head and fangs, the antennae, the dorsal delay and the smile board, the belly, and 15 pairs of feet and internal organs.

3. The code owned by the worm contains 15 pairs of feet, the feet near the head will be shorter, and the sequential feet along the tail will become longer in turn, and the last pair of feet will be the longest.

4. Worms generally inhabit human houses or near damp macro dead trees, and they have strong environmental adaptability.

Centipedes generally have 20 pairs of legs and 40 feet, and the number of feet varies depending on the species of centipede. In short, through the above content, I believe that everyone has an understanding of the problem of "what is a lot of legs like centipedes", and it can be known that the animal that has many feet with centipedes is called a worm, which is as poisonous as a centipede, and needs to be rinsed with alkaline water and a lot of soapy water after being bitten, and then disinfected with alcohol and iodine**.

Summary. Hello, it is the water centipede and the mussel shell insect (also known as the mussel shrimp) are aquatic pests that seriously harm the fish fry.

Hello, it is the water centipede and the mussel shell insect (also known as the mussel shrimp) are aquatic pests that seriously harm the fish fry.

And hemp. That's right.

Is there any harm to the human body?

Do I need to go to the hospital for a check-up?

Water centipede has two meanings. One refers to the larvae of dragon lice, which is more harmful to fish fry and contains a certain degree of toxicity. The other refers to plants, but there are many plants with this name, and it is impossible to generalize whether they are poisonous or not.

If it refers to a plant in the sedge family, then it is non-toxic.

If you don't use it, you can still catch it and eat it in some places.

Is there no problem with the numbness in the hands, and will it disappear naturally?

Hope, thank you.

will disappear naturally.

Don't worry, dear.

Centipedes are terrestrial arthropods.

Arthropods are a large group of animals and the most species-owned phylum in the kingdom Animalia, characterized by segmented limbs. There are about 110,120,000 extant arthropod species worldwide, accounting for 75,80% of the total extant species. They live in a wide range of environments, whether it is seawater, fresh water, soil, or the air, and some species also parasitize other animals in or outside the body.

Centipede belongs to a kind of terrestrial arthropods, the body structure of centipede is very distinctive, the body is composed of a segment, each segment has a pair of feet, one on one side, therefore, it is also called a multi-legged thing, a centipod, also called a dragon. The centipede is a species of poisonous terrestrial arthropod and does not belong to the class of insects.

The two sides of the arthropod are symmetrical, the heterorhythmic segmentation, the body and foot segmentation, can be divided into three parts: chest, head, and abdomen, each segment has a pair of appendages, and the body of the entertainment beetle is composed of several segments, so the centipede is an arthropod.

Arthropod Introduction:

The phylum Arthropod is the largest phylum in the animal kingdom, commonly known as arthropods, including well-known shrimps, crabs, mosquitoes, flies, butterflies, spiders, centipedes, and extinct trilobites. Arthropods are symmetrical on both sides of their bodies. It is composed of a column of body segments, which can be divided into three parts: head, thorax, and abdomen, or the head and chest are healed into cephalothorax, or the chest and abdomen are healed into the torso.

Pinouts. For example, the body of an insectoid is divided into three parts: head, thorax, and abdomen; The body of the subphylum Crustacea is divided into two parts: cephalothorax and abdomen; The body of arachnids is divided into cephalothorax and abdomen; The body of Myriapod is divided into a head and a trunk. The divisions of the body also have a division of labor in physiology, with the head being the center of sensation and feeding; The chest is the center of movement and support; The abdomen is the center of nutrition and reproduction.

Most arthropods are dioecious and tend to be dioecious. Terrestrial species often undergo in vitro fertilization, while many aquatic species undergo in vitro fertilization. It is generally oviparous, but there are also ovoviviparous.

The method of cleavage is epifissure, and there is direct and indirect development of the clump. Indirectly developed species have one or several different larval stages, and sometimes these larvae have different habits than adults.

There are also arthropods that are capable of parthenogenesis, in which an unfertilized egg develops into an adult. In addition, there are forms of larval reproduction and polyembryonic reproduction. Arthropods do not reproduce asexually.
