Halimeda beds in the shallow mesophotic at Ashmore Reef. These habitats are home to a diverse array of marine species and contribute greatly to the diversity of the reef.
A wide diversity of tiny cryptic fishes are associated with lagoon bommies in the Coral Sea and at Ashmore Reef (NW Network), including the Neon Eviota (Eviota atriventris).
Communities at the northern sites at Ashmore Reef were worst affected by bleaching in 2016/17. Recently dead foliose corals were observed at this northern site in 2017.
Pleurosicya mossambica also known as the toothy goby or the Mozambique ghost goby is found on many substrates, including corals, sponges, giant clams and seaweeds, and can vary colour according to the substrate.
