The distribution of epiphytic algae and sessile invertebrates on the seagrass Amphibolis griffithji is not random. The number of epiphyte species increases with increasing seagrass height and there are approximately twice as many epiphytic algal species as Invertebrate species. Epiphytes growing on the stems have a clear apico-basal distribution, with algae such as Haliptilon roseum, Laurencja filiforrnis and Hypnea spp. most abundant on the upper 30 '10 of the seagrass stem, while the bryozoan Celleporjna sp and the hydrozoan Thyroscyphus margjnatus are most abundant near the base of the stem. Other species of algae and invertebrates have intermediate distributions. Eplphyte biomass increases with seagrass height and the bulk occurs on the uppermost 20 cm of the tallest plants. This is mainly due to 1 or 2 algal species. Recruitment of epiphytes also follows a distinct pattern related to plant size (age), with species such as the crustose coralline algae rapidly colonising the leaves and stems of new seagrass plants. Other very early colonisers are the bryozoans Pyripora potita and Electra flagellurn on the stems, and the hydrozoan Plumularia compressa and the bryozoan Thairopora mamjllaris on the leaves.

“…In the shallow waters along the coasts of the bays and islands, Zostera grows thickly at places (FusE, 1962 a;KITA and HARADA, 1962), and the maximum standing crop of 2,352 gr wet weight per square metre in winter is given for the inner part of the Kasaoka Bay by KITA and HARADA (1962). The Zostera belt extends rather deeper when it occurs along the sandy shores of island in the middle of the sea, and grows longer blades.…”

“…Few studies have tested for habitat preference in motile macrobenthic invertebrates (Giles and Zamora, 1973;Van Dolah, 1978) although reports on habitat associations are widespread in the literature. Fauna1 associates of particular marine algae (Sloane et al, 1961;Hagerman, 1966;Norton, 1971;Fenwick, 1976;Moore, 1978) and seagrasses (Kita and Harada, 1962;O'Gower and Wacasey, 1967;Nagle, 1968;Santos and Simon, 1974;Stoner, in prep. a, b) by animals for particular macrophytes or for the cues which attract them to certain plant substrata.…”

Laboratory experiments showed that the three epifaunal amphipods Cymadusa cornpta, Grandidierella bonnieroides, and Melita elongata, normally associated with seagrasses, are capable of detecting small differences in the density of seagrass and actively select areas of high blade density. When different seagrass species -Thalassia testudinurn, Syringodiurn filiforme, and Halodule wrightii -were offered with equal blade biomass, H, wrightii was selected due to its high ratio surface area: biomass. When offered equal surface area all three amphipod species were randomly distributed among the seagrass species, confirming the hypothesis that surface area is the habitat characteristic chosen. It was concluded that blade surface area of macrophytes provides the best estimate of habitat complexity in seagrass meadows. The surface area relationship also held for C. compta when the highly branched red alga Gracilaria foliifera was used as a substratum. Degree of habitat selectivity by the three species of amphipods was related to known differences in vulnerability to predation by Lagodon rhornboides. It is concluded that habitat preference and biological interactions must both be examined to fully understand distributional patterns in seagrass epifauna.
