Images of Autonomous Reef Monitoring Structures (ARMS) and ARMS plates. Images show an ARMS in situ (A) and nestled within the reef after 2.5Â years of deployment (B). A light-exposed ARMS top plate, from which the benthic photosynthetic community was sampled, can be seen in (C). A Tethya sp. sponge (1) and a Halisarca sp. sponge (2), commonly observed on recovered ARMS, can be seen in (D). An internal light-limited ARMS plate with crossbars, which create sheltered conditions and mimic the natural reef, can be seen in (E)
