The Biology of Nematocysts is derived from a symposium dedicated to the exclusive discussion on the biology of nematocysts and cnidocytes. This book is basically a collection of the submitted reviews of contributors and research proceedings presented at the symposium.

An introduction on the recognition and discovery of both cnidarians and nematocyst aptly begins the discussion in the book. The first chapter serves as an advanced reading that helps readers be familiarized with the terms used in the entire volume. The following chapters are subdivided into six parts, including topics on the ultrastructure, development, control and morphodynamics of discharge, biochemistry, and natural history. The multidisciplinary approach of the main themes is intended to fully understand the unique qualities of the intracellular structure of nematocyst.

This volume will be of great benefit to students and researchers in biological science, cell biology, zoology, microbiology, and general physiology.
