Nudibranch and Sea Slug Identification 2nd Edition

This book illustrates 2,138 Indo-Pacific opisthobranchs, including many un-described species. With the evolution of chemical defenses and the loss of the shell, came the evolution of the bright color patterns that are the signature of nudibranch diversity; vivid colors advertise the presence of toxicity or distastefulness. All of this beauty and color is on full display in 2,500 photographs on 452 pages.
