The distribution of epizoites on the hydroid Nemertesia antennina (L.)

Abstract

Studies on the distribution of epifaunal species on their host have concentrated on those of plants, particularly laminarian algae (Fowell, 1939; Ebling, Kitching, Purchon& Bassindale, 1948; Sloane, Ebling, Kitching & Lilly, 1957; Scarratt, 1961, Ph.D. Thesis, University College of Wales, Aberystwyth; Norton, 1971), Sargassum algae (Kato et al., 1961; Nishihira, 1971; Ryland, 1974) and eel grasses (Nishihira, 1968; Nagle, 1968). Recently, however, the distributions of the animals living on ascidians Microcosmus sp. (Monniot, 1965) and the bryozoan Flustra foliacea (L.) (Stebbing, 1971) have been investigated.
