Guide to Freshwater Invertebrates

This guide provides an introduction to their great diversity and the means to identify the many different types, from flatworms to beetles. A series of easy-to-follow keys, along with notes on ecology and distribution, allow identification of the more commonly encountered freshwater invertebrates occuring in Britain and Ireland, while 460 line drawings illustrate whole animals and the features of importance in distinguishing different groups. Identification is typically to family level, and beyond where this is straightforward to do so, with a bibliography of other keys and guides for those who want to pursue identification further.
