Animals are one of the greatest things on Earth, and yet we often fail to appreciate them in all their forms. Every day, new species and life-forms are being discovered all across the globe, and they bring with them an ever increasing spectrum of variety. Many animals have their own unique identities, and these traits have always proven fascinating to us. From fierce to playful, instinctive to trained, animals play a vital role in the world we live in. They bring out both the best and the worst in people, and a personís attitude towards animals can often be a strong indicator of their nature.
