Biology of bryozoans /
Biology of Bryozoans covers some of the unusual and even unique systems and aspects of bryozoans. The book discusses the gametogenesis of bryozoans; the brooding patterns of bryozoans; and the structure and classification of gymnolaemate larvae. The text also describes the metamorphosis, ancestrulae...
