Invertebrate Embryology and Reproduction deals with the practical and theoretical objectives of the descriptive embryology of invertebrates, along with discussions on reproduction in these groups of animals. It explains several morphological and anatomical expressions in the field and covers the embryology of invertebrate animals, starting from the Protozoa, to the Echinodermata, the Protochordate and Tunicates. These groups include economically important aquatic invertebrates, such as crustaceans, as well as medically important invertebrates and economic arthropods. Each chapter is preceded by the taxonomy of the discussed phylum and/or the species to enable the reader to locate the systematic position.
- Covers phylum definition, general characteristics, classification, reproduction, agametic reproduction, gametic reproduction, spawning, fertilization, development and embryogenesis
- Includes recent findings in the area, along with detailed figures and photos that illustrate important concepts
- Brings together difficult-to-obtain research data from the field, not only in Egyptian libraries, but globally, and previously only found through specialized references not widely available
- Clarifies descriptions with striking photos and electron microscopical studies of different species
Researchers in the field of crustacean reproduction biology, invertebrate reproductive biology, invertebrate physiology, zoology, comparative reproductive biology and endocrinology, evolutionary biology, aquaculture, animal behavior, and advanced UG/grad students and instructors in these areas. Aquaculture practitioners will also find it useful for their hatchery operations.

Dr Fatma Mahmoud El-Bawab received her MSc and PhD in Zoology and is currently a full professor Alexandria University in Egypt. Throughout her career, she has contributed abundantly to the research in this zoology, specifically on male reproduction, spermatophores and development in invertebrates. She was the first staff member in Egypt to prepare and teach a curriculum for this specialized field and continues teaching the Invertebrate Embryology courses many years later. This experience has provided the basis for the development of the current specialized school of researchers and lecturers in this branch in the department.
