Explore ten of the world's most diverse environments and reveal their hidden secrets with a magic coloured lens that illuminates each page in a kaleidoscope of colour. Discover the dark and mysterious creatures of the night, whose super-sensory powers allow them to live and survive in the shadows, then switch the lens to step into daylight, where the heat of the sun supercharges the secret lives of creatures big and small. Finally, use the third lens to reveal the luscious plant life of every habitat as you travel through a jungle, a reef, grasslands, woodland and uncover a world that never sleeps. This is an animal book like no other, allowing you to view the natural world in full technicolour.
