A case of associated occurrence of the crab Lauridromia inter-media (Laurie, 1906) (Crustacea: Decapoda: Dromiidae) and the actinian Nemanthus annamensis Carlgren, 1943 (Anthozoa: Actiniaria: Nemanthidae)

Members of the crab family Dromiidae tend to cover their carapace mostly with sponges or colonial tunicates. More rarely are used other objects or organisms such as solitary Tunicata, Zoantharia (= encrusting anemones), valves of Bivalvia, etc.; a review of these is presented. A new association of a dromiid crab Lauridromia intermedia (Laurie, 1906) and an actinian Nemanthus annamensis Carlgren, 1943, is described and discussed. Lauridromia intermedia is recorded for the first time from the continental shelf of East Africa.
