Micro-habitat and Associations

 

Micro-habitat

Ophioplocus imbricatus was found exclusively under coral boulders in the reef crest zone specified in Local Description. Boulders were overturned and individuals were found on the sand underneath with some individuals found attached to the underside of the rock and are able to lodge themselves in crevicesinside these boulders (Figure 1). Although O.imbricatus individuals were relatively easy to locate, finding 8 individuals within a time period of 1.5 hours, the animals were commonly found in isolation with only one instance of 2 brittle stars occurring under the same boulder. Therefore no aggregatory behaviour was observed during collection.

Associations



Other fauna occurring in these micro-habitats beneath boulders were mainly sessile organisms such as sponges, ascidians and sedentary polychaete worms (Figure 2).
