Five things you may not have know about rodents

Mice and their poor eyesight
Mice are known for their extremely well-developed hearing. This allows them to detect movement from up to twenty meters away. As for their eyesight, it is a slightly different story. Mice are short-sighted and their sharp vision ends past half a metre. Also their colour vision is limited as they are naturally dichromatic - there are only two spectral cone types that are sensitive to blue or green light, and they completely lack the receptors for perceiving red colour. Due to their small black eyes, which are very sensitive to bright daylight, these tiny fluff balls are active mainly at night or they prefer dark nooks and crannies. As you probably know, it is difficult to catch sight of them during the day.

Mice, rats and their memory of an elephant
Do you know why are rats and mice regularly used for various tests and experiments? It is because of their incredible memory. And compared to other animals, they are highly trainable. One of the reasons scientists often use them for their experiments is that they always remember the way to their food. 

No need to drink
How is it possible that mice do not need to drink much? They hydrate through food. Yes, for example, they get water from grains. However, this does not change the fact that, unlike other creatures, they are able to find water almost anywhere. 

Rodents' front teeth - their biggest asset
The absolutely unique feature of rodents are their front teeth. They grow continuously throughout their whole life and because they can grow by up to 15 centimetres a year, rodents regularly grind them. These small mammals keep their two pairs of sharp and strong incisors in a good condition, mainly because they use them not only for eating but also to gnaw through various openings, wood as well as plastic or concrete. Teeth are therefore rodents' most frequently used body part.

Rodent - a sociable creature
Wherever you see one, you can expect many others. There is a simple rule that applies to rodents - they form colonies. They are sociable creatures. Same as bees they also prefer to work in groups and divide work within their colonies. It is rare for an individual to move away from its base.
