In this amazing world, there are many animals. Most of them are carnivorous, such as tiger, lion, cheetah, bear, and so on. These animals belong to land animals, but there are also marine animals, such as sharks, various types of whales, sea lions, seals, and walruses, and so on. But it should be clarified that not all animals are carnivorous; there are also herbivorous animals like yaks, zebras, giraffes, etc., that feed on grass around them, not other animal flesh. Each animal has its own lifestyle, and the life span of each is different. For example, tigers, lions, and cheetahs typically live from 20 to 25 years old under normal surrounding conditions, which is relatively short compared to human life. In the wild, the lifespan of animals is often shorter. There are also some very rare animals that are listed in the Red Book, and hunting them is punished by various laws. In order to ensure their reproduction and survival, there are special protected areas and different living conditions for these animals. For example, the Amur leopard - this type of animal is extremely rare as there are only 100 left, and a protected area has been established in a specific area to ensure they won't become extinct. There were once some animals that humans could not even imagine. These animals went extinct 20 billion years ago and most of them were carnivorous. The scariest animals were the dinosaurs. Their length could reach more than one kilometer, and their weight was over two tons. They were the first animals that appeared on Earth.
