CSIRO’s research vessel (RV) Investigator enables exploration of the deep-sea and ocean abyss of Australia’s expansive marine territories. Since the ship was commissioned in 2014, scientists have discovered and studied many extraordinary creatures adapted to living under immense pressure in the dark, cold water several kilometres below the surface of the ocean. This cover features just a few amazing animals of the deep found during RV Investigator research voyages. These include the monkey brittle star (Amphiophiura bullata), a king crab (Neolithodes bronwynae), and the threadfin dragonfish (Echiostoma barbatum). The reverse of the $1 coin depicts RV Investigator, CSIRO’s deep tow camera, along with a brittle star (class Ophiuroidea), gold coral (genus Chrysogorgia) and a king crab (Neolithodes flindersi).
