What is the smallest mammal, the smallest mammal

1. The smallest mammal in the world, so small that you can't find it, and it never weighs more than 5 grams!

The smallest mammal is the bumblebee bat.

The bumblebee bat is a large bumblebee bat in Thailand, with a maximum size of only 1 inch, and this miniature mammal has a wing extension of only 8 centimeters, belonging to the insectivorous bat class, which feeds on small insects flying in the air.

Weighing only 2g, bumblebee bats are the smallest mammals, this miniature mammal can hover in the air like a hummingbird, and like all bats, they prefer to inhabit cave environments and like to feed on insects. Due to their small size, they can easily perch on the tip of their thumb. Discovered in 1974 and inhabiting limestone caves in Thailand, this bat is considered one of the 12 most endangered species in the world, with only 200 bumblebee bats remaining in the world.

The smallest mammals: Etruscan shrews, jerboas, bumblebee bats.

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.

The 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.

Mammals are a part of the earth's creatures, and their appearance is very diverse, some mammals are huge, and some mammals are tiny, so do you know what is the smallest mammal in the world? The smallest mammal in the world is only 6 centimeters in length and weighs 5 grams, which is not as big as some praying mantises. Because it resembles a newborn mouse, it is named a stinky mouse.

Let's find out together!

First, the appearance characteristics.

It is the smallest mammal known in the world and one of the ten most interesting animals in the world. They are only 4 to 6 centimeters long, 4 to 5 centimeters long, and weigh only 1 to 5 grams. It is very similar to a mouse, with a very soft coat, a flattened head, a very small brain capacity, very low intelligence, and although the eyesight is not very good, the sense of smell is very sensitive.

There are branches all over our country, which are called stinky rats by the people.

2. Habits.

Although they are the smallest mammals in the world, they are veritable big eaters, consuming at least three times their body weight every day. They also have a special means of protecting themselves, as they have glands under their jaws that secrete venom to attack predators. If a human is accidentally bitten by it, the wound will become hot and swollen, causing severe swelling and pain, which will not disappear until a few days later.

And if a smaller animal is bitten, there is a high chance of death. But when they can't escape, they will pretend to attack or play crazy to scare off predators.

3. When did it appear.

You are the smallest mammal in the world and the first placenta-like to have been seen since the Mesozoic era of the Cretaceous period. They often feed on small animals such as insects and are also called insectivorous rats. Although it may seem very inconspicuous, the insectivores to which it belongs are the key to the important role in the evolutionary history of mammals, and are the most primitive and oldest of the placental mammals, which means that they are the ancestors of most of the higher mammalian groups, including primates.
