This book is the first of two books about sea urchins (echinoids) since 1953 (Th. Mortensen). The detailed and coloured illustrated descriptions enable the reader to identify all species living today in our oceans. Recent scientific searchings are included. Volume I. describes the sea urchins with pentameral symmetry and either with a few spines (cidaroids) or with more or less numerous spines ("regulars") living on the sea floor.
