This book condenses more than three decades’ worth of research and published information about the crab Neohelice granulata. It also serves as a reference book for any researcher studying the biology of crustaceans, and even a reference for other disciplines in which the species serves as a representative model. The study will also be useful to undergraduate and postgraduate students seeking to improve their knowledge of crustacean biology. The topics covered by this first volume include embryonic and larval development and ecology; sexual maturity, mating and fecundity; population dynamic; inter-specific and trophic relationships; parasitism and symbiosis; feeding ecology; and the ecological role of Neohelice granulata in the ecosystem.
