Seasearch Guide to Bryozoans and Hydroids of Britain and Ireland

Bryozoans and Hydroids are two groups of marine animals that are unrecognised by the majority of divers and frequently confused with each other, even though they are taxonomically distinct. When they are recognised at all, they have often been given confusing names such as ross coral or hornwrack which suggest they belong in completely different groups of animals and plants. However, they are both important groups and often form the major part of the animal 'turfs' that cloak our rocky reefs or encrust on boulders, cobbles and pebbles.
 This book aims to help non-specialists identify bryozoans and hydroids they see underwater, with the emphasis in recording in situ and thus making the minimum impact on the living reefs of which they are a part.
 This book has been produced as a part of the Seasearch project, which offers training in the identification of marine life and habitats and encourages recording by volunteers. Our aim is to improve your recognition of bryozoans and hydroids and thus improve the quantity and quality of records we receive.
 Features of the book include:
 - Over 120 species described in detail using photographs and text, with information on size, habitat and distribution.
 - Both scientific and common names used where they exist
 - Species grouped by form wherever possible, to aid identification
 - Additional information on features, classification, feeding, reproduction and ecology of both groups
 - A glossary of terms used to describe each group.
 The author, Dr Joanne Porter, is a Senior Lecturer at Heriot-Watt University in Edinburgh and her research speciality is bryozoans. She is a regular Seasearch recorder and has tutored both general Seasearch courses and specialist courses in bryozoan and hydroid identification. The great majority of the photographs and drawings in the guide have also been provided by regular Seasearch participants.
