The spherical test and impressive spines of a sea urchin. Coelopleurus floridanus. The mobile spines offer protection from predators. Since this species lives in relatively deep water, the purpose of the bright pigments in the skin and underlying skeleton is unknown. Photo by Arthur Anker.

We’ve all grown up learning about familiar animals like fish, tigers, elephants and bears, but this new book from Ross Piper takes the opposite approach: exploring the diversity in size, shape and color of the world’s most obscure and rarely seen organisms. With photography from Alexander Semenov, Arthur Anker, and other animal specialists and researchers, the 320-page Animal Earth promises to open your eyes to a variety of truly bizarre species from deepest oceans and the most adverse climates. The book is set to be published mid-November from Thames & Hudson.
