It is no secret to anyone that human beings are mammals, we belong to the group of vertebrate animals whose females have mammary glands that serve to feed their young. Next to us we find animals such as gorillas, chimpanzees, dogs and cats, among others of greater and lesser size.
Steps to follow:
The smallest mammal in the world is the shrew, an animal that at first glance could resemble mice but is not a rodent, but according to scientists very possibly descends from the mole or hedgehogs. It is characterized by its long muzzle and very small eyes and, of course, by its small size.
The shrew has a body that can measure between 3 cm and 5 cm and a tail that varies between 1 cm and 2 cm, which means that this animal does not normally exceed 7 cm, really small for a mammal!
And not to mention its weight, which usually ranges between 2 and 3 grams, so light that you will not even notice it in your hand.
The smallest mammal in the world has tiny eyes that do not allow it to see too clearly, which is why its whiskers are so important, as they allow it to orient itself in space. The shrew is native to central and northern Africa, although we can currently find it widespread in Europe, Asia and America.
In fact, in the Asian continent lives a species, known as the house shrew, which is the one with the largest size: about 15 centimeters in length.
What is most impressive about the smallest animal in the world is the enormous amount of food it eats for its weight and size. The shrew eats approximately every two hours because it has a very fast metabolism, and can get to ingest its own weight in food, something quite surprising.
It is also interesting to know that it is also the most active mammal, and that shrews hunt both day and night, fighting fiercely to get food, which is basically composed of insects. They will be small, but very brave.
