Demersal zooplankton are those animals that migrate at various times between the benthic and pelagic environments. Previous studies have concentrated on coral reef habitats (e.g. Emery, 1968; Porter, 1974; Alldredge and King, 1977; Porter and Porter, 1977; Porter et al., 1977; Hobson and Chess, 1979; Ohlhorst and Hutchinson, 1979). Inverted funnel traps were used by Thomas and Jelley (1972) to study demersal zooplankton in an estuarine ecosystem. King and All- dredge (1978) reported on the emergence patterns of demersal zooplankton from a subtidal sand-flat. Diel changes in zooplankton composition over an intertidal eelgrass flat were monitored by Robertson and Howard (1978).
