Are snails insects?

Question 1: Are snails insects? There are several basic unique forms of insects.

Adults, the body consists of three parts: head, chest and abdomen, and each part has appendages. Head: Located at the front end of the body, it has tentacles, compound eyes, one eye and mouth interaction, so the head is the center of insect perception and feeding. Antennas are sensory organs, which are often used to find food, courtship and avoid enemies. They also have sensory and auditory functions.

Snails do not have these characteristics, so they are not insects. They belong to mollusks. Snails have teeth and digestive system, which are different from coelenterates.

It has not been found that terrestrial animals can live with digestive cavities.

Question 2: Are snails insects? No, snails belong to Gastropoda terrestrial mollusks, and there are many kinds all over the world. According to relevant data, there are 40,000 species of snails in the world. Snails are distributed in all provinces and regions of China, living in forests, shrubs, orchards, vegetable gardens, farmland, houses, parks, gardens, temples, mountains, plains, hills and other places. However, there are few species with feeding and edible value. Snail, as a kind of human food and animal protein feed with high protein and low fat, has attracted more and more attention.

Snail's whole body includes shell, head, neck, shell membrane, feet, viscera, capsule and other parts. The spiral shell on its back has different shapes and sizes, such as pagoda shape, gyro shape, cone shape, spherical shape and pipe shape. At present, white jade snail, covered snail, scattered snail, open snail and brown cloud agate snail all have their own unique shapes.

White jade snails like to live in a dark, humid, loose and humus environment, lying down during the day and coming out at night. It is most afraid of direct sunlight and sensitive to environmental reactions. The optimum environment is 16 ~ 30℃(23 ~ 30℃ is the fastest). Air humidity 60% ~ 90%; The humidity of the feeding soil is about 40%; The pH value is 5 ~ 7. When the temperature is lower than 15℃, it will hibernate when it is higher than 33℃, and it may freeze or heat to death when it is lower than 5℃ or higher than 40℃.

Snails eat a wide range of food, mainly vegetables, weeds and melon skin; Leaves, stems, buds, flowers and juicy fruits of crops; Eat all kinds of grass and green tree feed, juicy feed, bran feed and cake feed.

Snails enjoy the reputation of "soft gold" in the world. Its meat is tender, delicious and nutritious. According to the determination, every 500g of snail meat contains 90g of protein and various nutrients needed by human body, such as amino acids, vitamins, calcium, iron, copper and phosphorus. It is a food with high protein and low fat. Snails are cold and salty. It has the effects of clearing away heat, relieving swelling, detoxicating, promoting diuresis, relieving asthma and softening hard mass. It has a certain curative effect on diabetes, cough, pharyngitis, mumps, scrofula, sore pain, hemorrhoids, centipede bites and other diseases, and is praised as a delicious food and a good health care product by consumers.

Insects, like other organisms, have their own special taxonomic status. It belongs to Insecta of Arthropoda in the animal kingdom. Its main features are as follows (imitation color map):

(1) Body links are divided into head, chest and abdomen.

(2) The head is the center of sensation and feeding, with mouthparts (mouth) and 1 pair of antennae, usually with compound eyes and monocular eyes;

(3) The chest is the sports center, with 3 pairs of feet and generally 2 pairs of wings;

(4) The abdomen is the center of reproduction and metabolism, which contains genitals and most internal organs;

(5) In the process of growth and development, insects have to undergo a series of internal and external morphological changes before they can be transformed into adults. This change in posture is called metamorphosis.

Therefore, the basic characteristics of insects can be summarized as follows: "the body has three sections: head, chest and abdomen, two pairs of wings and six feet;" 1 The pair of antennae are born in the head and the bones are wrapped in the body; There are many changes in life forms all over the world. "

Question 3: Are snails animals or insects? Snails are animals, and animals, plants and microorganisms are the three major creatures in the world. Insects are pests, that is, insects with wings and six legs. Snails belong to mollusks, including snails and earthworms. Snails belong to omnivores.

"

Question 5: Snails and flies belong to insects, because they both have tentacles, right? Speaking of insects, maybe we are already familiar with them. Colorful butterflies, bees visiting flowers to make honey, silkworm babies spinning cocoons, cicadas singing loudly, competitive crickets, fireflies shining with stars, dragonflies with superb skills resembling airplanes, simple and lovely ladybugs, mantis with a big knife in hand, annoying flies, mosquitoes, cockroaches and so on. So, what do insects have? Are spinning spiders and spiny scorpions insects? What about horses and centipedes? You may not be able to answer all these questions. Now let's see what kind of insect is an insect. Insects, like other organisms, have their own special taxonomic status. It belongs to Insecta of Arthropoda in the animal kingdom. Its main features are as follows: (1) The body link is divided into head, chest and abdomen, but they are not divided. (1) The head is the sensory and feeding center, with mouthparts (mouths) and 1 pairs of antennae, usually with compound eyes and monocular eyes; () The chest is the sports center, with opposite feet and generally opposite wings; () The abdomen is the center of reproduction and metabolism, which contains genitals and most internal organs; () In the process of growth and development, insects have to undergo a series of internal and external morphological changes before they can be transformed into adults. This change in posture is called metamorphosis. () The chirping insect is male, but the female can't. Therefore, the basic characteristics of insects can be summarized as follows: "the body has three parts: head, chest and abdomen, but only enough for wings;" 1 The pair of antennae are born in the head and the bones are wrapped in the body; There are many changes in life forms all over the world. " With the concept of insects, you now know the answer to the last question: spiders and scorpions are not insects, because their bodies are divided into head, chest, abdomen and legs. Scolopes and horses have more legs, and almost every link (body segment) has 1 ~ feet, not to mention insects.

Question 6: Snails are not insects. Insects have several basic and unique forms.

Adults, the body consists of three parts: head, chest and abdomen, and each part has appendages. Head: Located at the front end of the body, it has tentacles, compound eyes, monocular eyes and mouthparts, so the head is the center for insects to feel and feed. Antennas are sensory organs, which are often used to find food, courtship and avoid enemies. They also have sensory and auditory functions. Snails do not have these characteristics, so they are not insects. They belong to mollusks. Snails have teeth and digestive system, which are different from coelenterates.

It has not been found that terrestrial animals can live with digestive cavities.

Question 7: Are snails all abnormal insects? Snails should be abnormal animals. Snails have no characteristics of insects. They are not insects. They belong to mollusks. Snails have teeth and digestive system.

A perverted animal is an animal that has undergone metamorphosis after embryonic development.

These animals have a very special larval stage, which is very different from the adult stage. Only after morphological and physiological changes can they develop into adults (metamorphosis).

Cephalopod direct development

Question 8: Do snails and chameleons belong to insects? According to the classification, snails are insects and chameleons are reptiles.

Question 9: Are snails insects? No, insects belong to the class Insecta of Arthropoda.

Snails are mollusks, gastropods.

Insects have six legs and wings.

Scientific name Suecineasp.

Door: mollusk,

Subclass: spirochetes,

Objective: Pedicularis,

Family: amber snail family

Genus: amber snail.

The shape is similar to that of cone snail, with thin shell, short spiral part, transparent or translucent, fragile and shiny, with 3 ~ 4 spiral layers, and the spiral layer of the body grows rapidly, yellow to amber. The stitches are shallow and inclined. The shell opening is large and oval, and its height is greater than its width. The mouth edge is thin, sharp and crisp. The body is short and big, so it is difficult to contain its body in the shell when it contracts.
