In order to survive in order to adapt to the environment, different creatures will undergo certain changes in the process of evolution, so different animals will appear with different outstanding points. Take dogs, for example. Their sense of smell is extremely sensitive, but their vision is not optimal. Of course, the organs of different creatures are also very different, and some animals are particularly outstanding in certain aspects. So what are the characteristics of the hamster's facial features, and whether it has a more prominent role.

Eyes: Generally, the eyes we see in hamsters are mostly pupils, and The white part of the eyes is mostly hidden under the eyelids. The eyes of Jakalia hamsters and Roborovsky hamsters are all black; the eyes of golden hamsters and Campbell hamsters are black, red, and grape red, and some of them have different eyes. rat rat.

Hamsters are nocturnal or twilight animals, so their dynamic vision is very poor. Because the eyes are located on both sides of the face, they have a wide field of vision, but one problem is that the focus is poor, and objects are just a blur of light and shadow in the eyes of hamsters. It is for this reason that hamsters cannot judge the distance from objects, so they often fall from high altitudes. In addition to poor ability to distinguish objects, rats are also poor at distinguishing colors.

Ears: Although hamsters’ eyesight is not very good, their sense of hearing and smell are quite sensitive. Hamsters have trumpet-shaped ears that can hear subtle sounds clearly. Their ears can rotate at a certain angle, allowing them to hear sounds coming from all directions. In addition, the range of sounds they can hear is far greater than that of humans. The sound frequency that humans can hear is between 20 Hz and 20,000 Hz, while hamsters can hear and emit sounds as high as 50,000 Hz, so rats and mice usually use Communicating at frequencies that are inaudible to the human ear. The sounds we are most likely to hear are those made by hamsters when they are fighting, excited, or uncomfortable.

Beard: The hamster’s beard is concentrated on both sides of the nose and is an important organ used to sense the environment and size and shape. As mentioned before, hamsters have poor eyesight and cannot see and feel objects near and far clearly. So when the mouse moves, the whiskers replace the function of the eyes: whether there are obstacles and the distance to the object in front, whether the size of the slit can accommodate its own body, etc. Whiskers are as important to rats as radar antennas and should never be cut off with scissors.
