1. Agouti is a very successful mammal in the order of rodents. It lives in Central America. Its front teeth are enamel and the back is dentin. sharp. Rodents are almost everywhere. Abbott squirrels live in the United States and like to eat acorns, but there are two types of acorns. White acorns sprout immediately, and they cannot be eaten once they sprout. Red acorns will not be eaten until next spring. just sprouted. Abbott squirrels will eat white acorns immediately when they find them, and most likely bury them to store grain for winter when they encounter red acorns. But sometimes it happens that there are very few red acorns, and then they will bite the white acorn and hide it, because it bites off the embryo on the top of the acorn, so the acorn will never sprout. .
2. Rodents have also evolved corresponding strategies for the case of relatively small seeds. In the Mojave Desert of California, Genglu's cheek pouches can collect hundreds of seeds at a time, and the collected seeds are returned to the cave. Buried for safety. Other rodents like to eat whole plants, and alpine marmots sometimes fight each other for the grass plate. They are emotionally single and stay with their mates for life. Often daughters are bullied by their mothers, or even miscarried if they become pregnant, because during hibernation, parents can only keep one cub warm for the winter.
3. Some rodents are good builders. Beavers in North America like to build dikes. They bite down edible branches and then dive into the water to insert the branches into the dikes. The branches can be preserved in cold water until winter for enjoyment. Sometimes muskrats are also found where the beavers live, and they come with a pinch of fresh reeds, perhaps this is their rent to the beaver landlord. African crested porcupines like to hunt for food at night, and the spines on their backs serve as defensive weapons. Unlike porcupines, Bach's ground squirrels rely on collective strength to work together to care for their young.
4. Nude hamsters living in Kenya, Africa, adopt a unique breeding method to ensure the prosperity of the race. A nude hamster family has a queen, and other members are descendants of the queen. As long as the queen is reproducing, the other members will Barren, they are responsible for burrowing in the ground to find food to raise young mice, in a similar way to bees and ants, but only the nude hamsters follow this method among mammals. The Patagonian rabbit and guinea pigs reproduce at a moderate rate, and the young children of a family are uniformly cared for. They run and eat grass on the grasslands, and have evolved long legs. They look like antelopes from a distance. This is also the reason. They are not good at digging. Rather occupy the burrowing owl nest.
5. The world's largest rodent, the capybara, lives in South America. It makes good use of its teeth to eat grass and has an amazing appetite. It can run on land and swim in water, and its speed can catch up with ponies. If the rabbit guinea pig is the antelope of South America, then the capybara is the hippo of South America, and the capybara is also known as the courtesan of the animal world.
