What is the fundamental difference between an animal and a bug?

The most fundamental difference is that mammals are homeothermic and insects are ectotherms. There are also many differences in form, but that is for the function.

The fundamental difference is that mammals belong to the phylum Chordates – the subphylum vertebrates, while insects belong to the phylum Arthropods – the class Insecta, which means that mammals are vertebrates and insects are invertebrates.

Due to the differences between invertebrates and vertebrates, a series of differences are derived, such as: respiratory system type, digestive system type, excretory system type, nervous system type.

Personally, I think arthropods are invertebrates.

Whereas, mammals are vertebrates.

Cellular DNA permutations and combinations are different

Mammals are vertebrates and insects are invertebrates;

Mammals are homeotherms, and insects are ectotherms.

Bugs belong to animals.

Animals include bugs.

Bugs are a subclass of animals.

Aren't bugs animals?

Mammals are viviparous and insects are oviparous.

Insects are animals, among animals.

of a kind. To be exact, a class of arthropods.

Insects belong to invertebrates, belong to the phylum Arthropods and Insecta, and are the most diverse and largest class of extant animals, accounting for about 80% of all animal species.

The main characteristics of insects are: no spine in the body, with a chitinous exoskeleton to support the body; The body is segmented, the larval stage has limbs on each segment except for the cephalic segment (some also include the tail segment), and the adult stage body is divided into three parts: head, thorax, and abdomen, and the head has a pair of antennae and a pair of compound eyes; thorax with three pairs of legs, two pairs of wings (or one pair of wings, or no wings); There are no appendages in the abdomen. Breathe air directly through the valve trachea.

The insects we are talking about are generally from the phylum Arthropoda, such as spiders and centipedes, which are arachnids and myriapods of the phylum Arthropods, respectively. Whereas insects refer to the class Insecta of the phylum Arthropods. Insecta is the phylum Arthropod and the most diverse class in the animal kingdom, they are characterized by hexapods, no bones, the body is supported by a hard shell on the body surface, divided into three growth stages of eggs, larvae and adults, and the body is multi-segmented.

Spiders, centipedes, etc. are bugs but not insects. That is, insects are bugs, but bugs are not insects.

Insects belong to animals.

Animals contain insects.

Insects themselves are part of the animals, those species in the animal kingdom that belong to the class Insecta, and their common typical feature is that adults have six legs (three pairs), and the body is clearly divided into three parts: head, thorax, and abdomen.

We usually think that all bugs are insects, but in fact, this idea is wrong.

To find out whether a bug is an insect, it is necessary to identify it from the characteristics of its body. The body of all insects is divided into three parts: head, thorax, and abdomen, and there are three pairs of legs on the chest, which is the main feature of insects. Spiders and centipedes are not insects because the body of the spider is divided into only two parts and has 4 pairs of legs; The centipede's body is divided into a head and torso, and there are many uncountable feet, and it is certainly not an insect.

Most adult insects have a pair of antennae on their heads, which have the functions of touch, taste and smell, such as the tentacles of butterflies and parasitic wasps can sense tastes, the tentacles of male mosquitoes can sense sounds, and ants and bees can express meaning to each other when they touch their tentacles. The tentacles of different species of insects have different roles and functions.

In addition to one eye, the insect has one pair of compound eyes on its head.

Except for a few insects that do not have wings, most insects have two pairs of wings. In general, the front wings of the beetle become hard and cannot be used for flight, but can only be used to protect the hind wings and abdomen. There are also insects whose hind wings have degenerated, leaving only the forewings, like mosquitoes and flies.

The wings of different insects grow differently, the wings of dragonflies are transparent, and the wings of moths and butterflies are covered with patterned scales.

The animal kingdom is divided into 34 phyla (Protozoa, Annelids, Arthropoda, Mollusc, Hemichordates, Chordates, etc.).

According to the taxonomic hierarchy of kingdoms, phyla, classes, families, genera, and species, insects belong to the kingdom Animalia, the phylum Arthropods, and the class Insecta.

Insects and shrimps, crabs, spiders, and scorpions all belong to the phylum Arthropods, but they belong to different orders, like shrimps and crabs belong to the crustacean class, and spiders and scorpions belong to the arachnids, but one is the order Arachnida and the other is the order Scorpion.

When summer arrives, you can expect to see all sorts of critters that take advantage of the warm weather to fly, bite and scurry. But whether you're tolerant of these creepy little reptiles, or you're happy to never see them again, you're probably asking yourself: Which ones are bugs and which ones are insects?

Difference Between Bug and Insect

Bugs and insects don't necessarily refer to the same thing. While the two terms are used interchangeably, and insects are mostly found in scientific contexts, while insects are used casually, the difference between the two terms is not just in semantics. They both describe groups in the animal kingdom that are recognized by science.

Insects are more clearly defined than insects. Insectans are a class in the phylum Arthropods, which also includes arachnids like spiders, myriapods like centipedes, and crustaceans like crayfish. Insects, like all arthropods, possess segmented legs and a hard outer layer called an exoskeleton.

Unlike some other arthropods, insects typically have six legs, two antennae, and a body divided into three parts (head, thorax, and abdomen). Insects contain many organisms that you think are bugs. For example, ants, grasshoppers, bees, and flies are all insects.

Although all insects are insects, not all insects are insects by definition. True bugs belong to a class of insects called Hemiptera. There are a few characteristics that distinguish bugs from other insects:

Most bugs have a straw-like mouth that they use to draw sap from plants or blood from animals.

In addition, they tend to have long, segmented antennae and have wings that are tough and dark close to the body and thin and transparent at the tail. The real bugs include stinkbugs, bed bugs, water striders, and chiro. Confusingly, some insects with the word bug in their name aren't actually real bugs, such as ladybugs and June bugs (both of which are beetles).

From a linguistic point of view, the line between bugs and insects becomes blurred. Most people think of any small non-sea creature with more than four legs as a bug, and it ranges from spiders to beetles to millipedes. That's why entomologists would refer to Hemiptera members as real bugs and not just bugs :

Because even they themselves misuse the term in the usual way.

Insects are a type of animal that belongs to the arthropods among invertebrates.

Animals: Animals are a large group of multicellular eukaryotic lifeforms, as well as some single-celled organisms, called the kingdom Animalia. Animals are a large group in the biological world, generally can not synthesize inorganic matter into organic matter, can only feed on organic matter (plants, animals or microorganisms), so they have different morphological structures and physiological functions from plants, in order to carry out life activities such as feeding, digestion, absorption, respiration, circulation, excretion, feeling, movement and reproduction.

Insects: Insects are of great variety and morphology, belonging to the arthropods of invertebrates, and are the most abundant animal group on the planet, accounting for more than 50% of all biological species (including bacteria, fungi, and viruses), and their traces are found in almost every corner of the world. Until the beginning of the 21st century, there were more than 1 million species of insects known to mankind, but there are still many species yet to be discovered.

Insects are the most abundant group of arthropods, and the most common are locusts, butterflies, bees, dragonflies, flies, and grasshoppers. Cockroach. Wait.

Not only are there many species of insects, but the number of individuals of the same species is also staggering. The distribution of insects is so wide that no other class of animals can compare with it, and it is almost all over the earth.

Question 1: Are insects animals? It's animal.

Animals are a large category, and insects are a small classification under the animal class.

Question 2: Are bugs the world's first animals? 5 points The progenitor of all things is fish, not insects!

Question 3: What kind of animal is this? It is the largest group of species in the Hemiptera, with about 5,000 species in the world.

Question 4: What is the division of insects, and what else is there besides insects 5 points "Insects" in a broad sense are not only insects, or even not only arthropods, but also some flat animals, nematoids, mollusks, annelids, etc., and all insects with the word "insect" in their names can be regarded as insects in a broad sense; This is not a very strict definition, you must know that tigers also have the nickname "big worm".

Specific to arthropods, arachnids (spiders, scorpions, etc.), myriapoda (this is not a regular class, it is a general term for labiopoda, double-footed, etc.), hexapoda (including insects, springtails, etc.), some of the crustaceans (such as rats, horseshoe crabs, etc.) can be called "insects", and [insects] in a broad sense include all species of hexapods (scientists in some countries call other classes of arthropods also insects, regardless of that), and in a narrow sense, it refers to insects, like jumping insects, Protocercera, which fits the broad definition of an insect, is not strictly a member of the class Insecta.

In particular, I would like to introduce a special class of "insects", which contain arthropods and annelids, called "clawed animals", such as velvet insects, which can be seen by the landlord, which is very interesting.

Question 5: Are insects animals, just or not, thank you Insects are in the animal kingdom, you say yes.

Analysis: Cordyceps sinensis is not called a bug? What is called any insect is an animal, most of them are in the phylum Protozoa and Platyzoa, and there are also in the phylum Rophantas.

For example, the green eye insects of the subclass of phytoflagellates in the protozoan phylum Flagella, etc., the Phi Hair Worm in the Flagella subclass of the Flagella class, the collar whipworm, the protocotton worm, the variant whipworm, the trypanosomes, the Ducho Leyshmania protozoa, etc.; sunworms, radiolaria, etc., of the subclass radiopod of the class Sarpoda, amoeba of the subclass Rhizopoda of the genizopoda, amoeba of dysentery, etc.; Sporophyta: Intermediate Japanese protozoa, coccidia, rabbit liver, Eimeria hepatica, etc.; Paramecium, echinocercia, bell worms, etc. planarians in planarians of the phylum Planarians, etc.; the three generations of the monogeneous subclass of the class of trematodes, such as the ring Zhaoxiang S. canopia, etc., the Clonorchis sinensis of the subclass of the class Clonorchis sinensis, Fasciola brucei, Schistosoma japonicum, etc.; Taenia solium in the class Taenia, Taenia solium, Echinococcus granulosa, etc. nematodes: Ascaris, pinworm, haemophila, Trichinella, wheat nematode, etc.; Rotifers, animals, rotifers, etc., etc., etc., there are many and countless types.

For example, many species of molluscs have to go through the larval stage, and some of their larvae are called disc larvae; A small part of the feast is called the hook larvae; Annelids have larval stages, and their larvae are called trochal larvae; The phylum Coelenterates all go through the larval stage, and their larvae are called floating larvae.

When summer arrives, you can expect to see critters flying, biting, and escaping in warm weather. But whether you tolerate these creepy reptiles or are glad never to see them again, you're probably asking yourself: which ones are bugs and which ones are insects?

Bugs and insects don't have to be the same thing. The two terms are used interchangeably, with insects appearing primarily in scientific contexts, while insects are used more casually, but the difference between terms is not just semantic. They all describe groups in the scientifically recognized animal kingdom.

The boundaries around insects are clearer than those around bugs. Insects are a category within the phylum Arthropods, which also includes arachnids such as spiders, myriapods such as centipedes, and crustaceans such as crayfish. Insects, as well as all arthropods, have segmented legs and a hard outer layer called an exoskeleton.

Unlike some other arthropods, insects typically have 6 legs, 2 antennae, and a body that is divided into three parts (head, thorax, and abdomen). Insects contain many organisms that you tend to think of as bugs. Ants, grasshoppers, bees, and flies are all insects.

All bugs are insects, but not all insects are bugs by the technical definition. True bugs belong to a type of insect called Hemiptera. There are a few characteristics that distinguish bugs from other insects:

Most bugs have a straw-like mouth or stylet that they use to squeeze sap from plants or blood from animals. They also tend to have long, segmented antennae and wings that are hard and black where they come into contact with their body, with thin and translucent ends. True bugs include bed bugs, bed bugs, water striders, and cicadas.

Confusingly, some insects with bugs in their names aren't actually real bugs, like ladybugs and Junebugs (both of which are beetles).

From a linguistic point of view, the line between bugs and insects becomes blurred. Most people think of bugs as any small non-sea creature with more than four legs, covering everything from spiders to beetles to millipedes. This is why entomologists refer to the members of the order Hemiptera as real bugs and not just bugs, because even they feel guilty about using the term in a general way.
