Anonymous users2024-02-12The smallest mammal is the shrew, which is only 4-6 centimeters long, the size of a bee.
The shrew is only 4-6 centimeters long, and the tail length is 4-5 centimeters, which is not as big as a human thumb, and its weight does not exceed 5 grams, making it the smallest mammal in the world. This small shrew generally inhabits forests, and it is also found in the northwest of our country, and some people wonder why they have never been seen because it is so small that you can't find it.
Shrew history traces
Insectivores such as shrews may seem to be "inconspicuous" small animals, but they have played a very important role in the evolutionary history of mammals. They have appeared in the Upper Cretaceous strata of the Mesozoic Era, and are the most primitive and oldest of the placental mammals, and have played a pivotal role in the evolutionary history of mammals, and are the ancestors of most of the higher mammalian groups.

1. Etruscan shrew
The first to make the list is the Etruscan shrew, which has a long history of survival and has an amazing appetite, but it is extremely small, only about 4 centimeters long, weighs only about 2 grams, and looks like a rat to make people feel frightened. Insectivores such as shrews seem to be "inconspicuous" small animals, but they have played a very important role in the evolutionary history of mammals.
They have appeared in the Upper Cretaceous strata of the Mesozoic Era, and are the most primitive and oldest branch of placental mammals, and are the ancestors of most of the higher mammalian groups, especially primates including humans, rodents with the largest species and numbers in the world, bats that can fly in the air, etc., and pterocarps, etc., are directly differentiated from early insectivores.
2. Jerboas
Jerboas, also known as "desert mickey mouse", have a petite size, but large eyes and heads, a long tail, and a very camouflaged coat color, the smallest of which is only about 7 centimeters.
3. Bumblebee bats
The bumblebee bat is the smallest bat in the world, it has a small size, often mistaken for a bumblebee, with a pig-like nose, which looks very funny, and its wings are only about 8 centimeters, which is not as big as a human palm.
This is due to the fact that protozoa have the fewest genetic cells and the least developed ones, so they are called the lowest animals.
Organisms in nature are divided into 3 categories: animals, plants, and microorganisms, so the bottom is the microorganisms!
1. The smallest mammal in the world, so small that you can't find it, and it never weighs more than 5 grams!

The peach blossom jellyfish (craspedacusta sowerbyi), also known as the peach blossom fish, is the lowest level of organisms on the earth, the peach blossom jellyfish is the most primitive and lowest invertebrate coelenterate, which has been 6.5 billion years ago, and appeared hundreds of millions of years earlier than the dinosaurs. The peach blossom jellyfish has extremely high requirements for the living environment, the water quality can not have any pollution, the living body is rare, it is extremely difficult to make specimens, and it is listed as the world's highest level of "critically endangered species" by the state, and it is also known as the "giant panda in the water".
