An informative and well-illustrated book outlining some of the more horrible aspects of biology. In this book you will read about devastating pests; very nasty parasites; a lizard that squirts blood from its eyes; a centipede that catches bats; a farting beetle; venomous snakes; a microscopic animal that eats your brain, and of very brave people who used themselves to further the knowledge and understanding of diseases.

Although over two million different species of living things have been listed, and millions more to be discovered most are harmless to humans, but some are very horrible indeed, and not only cause disease and infections, but can also cause serious economic damage.
