INTRODUCTION

A common characteristic of alga-invertebrate symbioses is their specificity; in general, a given symbiotic invertebrate species forms a stable association with just one species or genus of alga. One approach to examine the basis and significance of the specificity is to compare the performance (i.e. survival, growth and reproduction) of invertebrates experimentally infected with a range of algae. To date, such investigations have been made almost exclusively with algae which do not naturally form an association with the host species (e.g. Schoenberg & Trench, 1980; Mews & Smith, 1982; Douglas, 1983), and the relevance of the conclusions to the natural situation is not always clear.
