Australian scientists are using robots to release millions of coral babies to regenerate parts of the Great Barrier Reef, damaged due to growing sea temperatures.

The coral babies, or larvae, were released this week after scientists from four Australian universities collected coral eggs and sperm from the reef and reared the babies in floating nursery pools until they developed polyps, the living part of the organisms.

The operation follows a successful trial of the robotic coral delivery system in reefs in the Philippines earlier this year, according to a joint statement released on Wednesday by the Southern Cross University, the Queensland University of Technology, the James Cook University and the University of Technology Sydney.
