Publisher's Synopsis
Aquarists, biologists, conservationists, ecologists, shell-collectors and a host of others will find this a useful title. Until now there has been no readily title information on southern African freshwater snails and mussels. Specialists and hobbyists alike will welcome this concise and up-to-date reference work - in particular the new key to the identification of the southern African species. The chapter on Bilharzia and its snail hosts is especially important at this time when Primary health care programmes are being implemented throughout South Africa, and access to safe drinking water is regarded as a fundamental human right.
