The rabbit's mouth is three-pronged. The rabbit's three-valve mouth is actually the result of evolution. Rabbit's food is all kinds of grass and grass roots. Rabbits have front teeth. Three-flap mouth is beneficial to whether the front teeth can be turned out when rabbits eat grass. When rabbits eat low grass, they will not be blocked by their lips, and their eating speed will be greatly accelerated.
The use of rabbit mouth, Fang Ran is used to eat! Then why is it a rabbit with three cracks? This should start with the eating habits of rabbits. In order to satisfy the eating habit of rabbits eating grass, the rabbit's third split mouth came into being. Rabbits and cows are both herbivores, so why are cows' lips thick? That's because rabbits like to eat grass roots and grass tips, and their skills are different How hard it will take to let the thick lips of cattle gnaw at the grass roots! Their thick lips are enough to block the way, and the rabbit's three-petal mouth is just right for this situation.
Because rabbits have long teeth, it is inconvenient for rabbits to eat grass roots. When the rabbit eats grass, it first opens its upper two mouths to expose two front teeth, and then bites the grass roots tightly with its teeth. This is the advantage of two upper lips. Eating grass roots is no problem. Having said that, some people may ask, why do rabbits have to eat grass roots? The grass is tender and fresh. Why not eat it? This is mainly related to the size of rabbits. Compared with herbivores such as cattle, horses and sheep, rabbits are just small people, and it is not easy to eat tall grass tips. They tried to find enough grass to eat for convenience. After eating the grass on the ground, they can only chew the grass roots. And with the three-flap mouth that can be opened, it is more convenient for them to eat grass roots.
This is the product of evolution. The ancestors of rabbits mainly ate grass and plant roots. Because these foods grow very low and close to the surface, clods will enter your mouth when you eat them. In order to avoid this situation, the rabbit's mouth is divided into three petals, and the quality of eating can be guaranteed by pressing one petal against the clod.
