Invisible Nature

There are sounds no human ear can hear, scents no-one can smell, colours our eyes cannot detect, waves of radiation that pass right through us without our noticing, but known and used by many different animal species. They have dangers as well as uses, but are vital to all life on Earth. This fascinating unseen and secret world is revealed in Catherine Barr's latest book.

Fourteen colourful spreads display the impact on human and animal life of microwaves; ultra-violet and infra-red light; electromagnetic waves; ultrasound and infrasound and scents and smells beyond human detection. Understanding these hidden forces enables us to use them in many ways. But many animals also use them. They help cats to catch mice, elephants to find mates, vampire bats to find victims. Ants 'talk' by exchanging smells. Indeed, without 'Invisible Nature', life on Earth would not exist at all.

"A stunningly visual non-fiction picture book for younger children, exploring the unseen but immensely powerful natural forces that govern life on our planet. A fascinating combination of natural history and scientific principles, using the lives of animals to explain it in a fun, clear way." The Bookseller - Back to School "A fascinating look at how creatures use light, scent, sound and forces beyond human senses." -- Fiona Noble The Bookseller
