Philip Lambert and William Austin describe and illustrate 34 species of brittle stars, sea urchins, and feather stars inhabiting the coastal waters of Puget Sound, the Alaska Panhandle, and British Columbia. As with previous Royal BC Museum Handbooks on sea stars and sea cucumbers, this book contains photographs and illustrations to help identify the species in each class: 24 brittle stars, 8 sea urchins, and 2 feather stars. The species descriptions provide all the details to satisfy the professional biologist, yet the easy-going style of the authors makes this book suitable for anyone interested in coastal marine life.
