The animal world is a diverse and rich world with millions of species of animals living across continents and in many different habitats. From tiny animals like ants, bees and mosquitoes to giant animals like elephants, whales and sharks, the animal world is an incredibly complex and magical world. Each animal species has unique characteristics and living needs, and they adapt to different habitats, from arid environments such as deserts and grasslands to aquatic environments such as seas, rivers and lakes. Many animals live alone, while others live in groups or herds. Some animals have the ability to change color or glow, but there are also species that have no eyes or no ears.
