Mammals are considered to be the highest class in the animal kingdom, what is the largest?

The largest mammal in the world is the blue whale, which is found in all seas around the world.

It weighs about 170 tons and can reach a length of about 30 meters. The head of the blue whale is very large, and it can stand up to 50 people on its tongue.

After a gestation period of about 1 year, the baby blue whale is generally born from its mother in winter. Newborn calves weigh tons and are meters long. The baby whale grows very quickly, usually about 100 kilograms within 24 hours of feeding the mother, an average of about 70 grams per minute.

By the time they reach 7 months, they can weigh about 23 tons and reach a length of 16 meters, and begin to learn to open their mouths to devour a variety of plankton. The baby blue whale grows into an adult after 5 years of growth. Adult blue whales generally live for 50-80 years.

No, mammals are not the most abundant animal species among animals.

There are more than 1.5 million species of animals still living in the world, and only 4,237 species of mammals have been discovered, accounting for only a very small part of the animal species.

Invertebrates have the largest number of living animals in the world. Among them, arthropods are the most numerous, with more than 1.2 million extant species, accounting for 80% of the total number of living species. Among the arthropods, it is the insect class that has the most species and the largest number.

More than 1 million species of insects have been discovered, and the largest number of individuals in a single species is ants, which are too numerous to count.

The most common of animals are insects, for the following reasons:

First, insects are of great variety and morphology, belonging to the arthropods of invertebrates, and are the most numerous animal groups 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.

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

Third, there are not only many species of insects, but also a staggering number of individuals of the same species. 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.

No, mammals are only a minority. Oviparous animals make up the vast majority.

The most abundant are arthropods among invertebrates, and the most abundant among arthropods are also insects.

The most abundant of animals are insects.

Insects belong to the phylum Arthropods.

The animals of the entire phylum Arthropod are 100 1w times the number of mammals.

Are you asking about the species of animals? If it's old common sense, it means that there are the most types of insects, but now I don't know.

Rodents are the most diverse group of mammals and the most widely distributed mammals, with about 2,000 species worldwide. The total number of mammal species is less than 6,000. Rodent species account for more than 40% of the total number of mammals.

Rodents include a variety of squirrels, chipmunks, jerboas, guinea pigs, hamsters, house mice, beavers, porcupines, groundhogs, etc. Insecta is the most diverse, largest and most widely distributed group in the animal kingdom It is known that there are more than 1 million species of insects on the earth, accounting for about 2 3 Insects belong to the animal kingdom and the phylum Arthropods Therefore, the most diverse, largest and most widely distributed animal group in the animal kingdom is arthropods;

The so-called mammals, as the name suggests, are animals that can secrete milk to feed the next generation, and the mammals are divided into protozoan subclasses and euzon subclasses, among which all euzo subclasses belong to the higher ones, so all mammals except for the protozoan subclass are higher mammals. The protozoan subclasses include platypus, kangaroos, koalas (koalas), thylacines, and many more.

Organisms are divided into high and low organisms in the order of evolution.

All primates are higher mammals.

Blue whale. The largest mammal living on Earth is the blue whale.

The blue whale is a marine mammal that belongs to the suborder Baleen Whales. There are four subspecies. The blue whale is huge, reaching a length of up to 33 meters and weighing 181 tons, making it the largest and largest mammal living on Earth.

The blue whale is also believed to be the largest animal known to have ever survived on Earth. Because some dinosaurs may have been longer than blue whales, but they were far inferior in size and weight to blue whales. Blue whale.

Mammals are homeothermic, vertebrate, hairy, mostly viviparous, and rely on mammary glands to feed their offspring.

The largest mammal on Earth is the Blue Whale.

A female whale caught in the waters of South Georgia in 1947, measuring 190 meters long and weighing 190 tons. According to statistics, the number of blue whales is less than 50, and it is on the verge of extinction. Humanity should be protected.
