The three orders of the most species rich animals are, and the one with the most species in the anim

The three orders of the highest species of animals are:

The three orders are rodents (mammals such as rats, porcupines, beavers, capybaras), pterocodas (bats), and true-blind deficients (shrews, moles, groove-toothed shrews, etc.).

The next three orders depend on the classification method chosen, which can be primates (e.g., apes, monkeys, and lemurs), cetacean artiodactyls (e.g., whales and artiodactyls), and carnivores (e.g., cats, dogs, ferrets, bears, seals, etc.). A total of 6,495 mammalian species are known, including 96 recently extinct species.

The three tallest animals in the world.

1. Giraffe (6-8 meters).

2. African elephant (

3. Moose (m).

Animals can be divided into terrestrial animals, aquatic animals, and amphibians according to their living environment.

The tallest animal in the world, the giraffe.

The most species-containing class in the animal kingdom is the arthropod The insect class in the arthropod kingdom is the most diverse, numerous, and widely distributed group in the animal kingdom According to this answer

Answer: Insects belong to the animal kingdom, the phylum of arthropods, and the class of insects, and are the most diverse, numerous, and widely distributed group in the animal kingdom There are more than 1 million species of insects on the earth, accounting for about 2 3 of the entire animal kingdom

Arthropods are the largest number of species in the animal kingdom, it is said that there are more than 750,000 species of insects named by humans, and there are 58,008 species verified and accepted by worms, and there are 4 subphyla still alive in the world, with a total of 17 classes, such as insects, arachnids, crustaceans, etc.; Their common features are limbs with segmentation, as well as the exoskeleton where the main component is chitin.

In the phylum Arthropods, the most diverse is fish, and the most diverse among the animals is the phylum Arthropods.

The most species-rich group in the animal kingdom is arthropods.

Phylum Arthropods.

Contains about a few million species in the largest number.

One of the most diverse insects in the animal kingdom.

The largest group in the animal kingdom is the class Insecta.

Insecta, formerly known as "Hexapods", is not only a phylum of arthropods, but also a class with the largest variety and number of species in the entire animal kingdom, and their traces are found in almost every corner of the world. There are now about 1 million known species of insects, but many species are still to be discovered.

There are many kinds of insects, different morphologies, and in the scientific division of the first jujube, insects are included in the phylum Arthropods, Hexapod Subphylum, which have the common characteristics of arthropods. Insecta is not only the largest class in the phylum Arthropods, but also the largest in the animal kingdom. 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.

Distribution

There are about 1 million species of insects in the world, some estimate 2 million species, and about 10,000 new species are discovered every year. There are about 12,150,000 species in China. There are many species of insects (about 80% of the species in the animal kingdom), with different habits and a wide range of distribution, except in the waters of the ocean, insects can be found in all areas where plants grow.

Insects have a strong ability to fly, and their tiny bodies are easy to spread with air currents, so they can be found from the equator to the poles. For example, butterflies have been found at 80°N, and mosquitoes have been found at 70°N; Insects have also been found in the Antarctic Circle. Hemiptera insects have been found in the mountains at an altitude of 5,029 meters, and wild lepidopteran insects have been found in the mountains at an altitude of 488 meters, and several wingless subclass insects tend to live at higher altitudes.

The upper limit of the distribution of insects is 6,800 meters above sea level. There are also insects in hot springs and caves.

Insects are a large group of organisms with the largest number of species, the largest number of individuals, the most diverse lifestyles, and the most peculiar survival strategies on the planet. At the most conservative estimates, there are at least 1 million species of insects in the world, and there may be 500 10 million species, or even 80 million species. Even in 1 million species, insect species account for almost 60% of all living species on Earth, 80% of animal species, 90% of invertebrates, and 95% of arthropods.

Insects are the absolute majority in the biological kingdom and are the dominant species. The vast majority of existing insects are small, and insects win by being small. Insects do not have vertebrae and rely on a tough chitin shell to support their bodies.

The small size can increase the relative area of the epidermis, thereby reducing weight and increasing strength, which is convenient for insects"See the stitches", occupying space where other species cannot survive. Insects are small and need to molt several times from egg to adult, making them vulnerable to a variety of predators, so they must be in sufficient numbers to meet the needs of population reproduction. Even the ferocious master of hunting mantis, is ensured by a large number of individuals.

An ordinary praying mantis will generally lay 2 or 3 egg masses (crickets) and can hatch hundreds to thousands of individuals. So the number of insects is very large.

No one can say for sure this estimate.

First, there are so many of them, and many encyclopedias have trade-offs, and second, new species can be discovered at any time.

Three, there are different ways of taxonomy in biology, and they all have different reasons, so can you tell us what kind of knowledge you want?

"Make a list of them, and tell me the number. "
