CIESM Publishers, Monaco. 192 pp. ISBN 92-990003-2-8.This is the second published volume of a new series launched by the International Commission for the Scientific Exploration of the Mediterranean Sea (CIESM). This series is devoted to providing the scientific community with a comprehensive survey of recent immigrant species into the Mediterranean either by natural or by direct, human-induced causes. Three main types of exotic species may be distinguished in the basin: those of Indo-Pacific origin having entered the Mediterranean via the Suez Canal, those of tropical Atlantic origin having entered the Mediterranean via the Strait of Gibraltar, and those of clear "accidental" introduction by man.Peer reviewed
