Researchers at Queensland University of Technology (QUT) in Australia have repurposed a drone to deliver coral larvae onto targeted reefs. The RangerBot is an underwater drone deployed in the Great Barrier Reef since 2018. This drone had previously been used to monitor reef status and protect coral from predatory starfish. Researchers first collected hundreds of millions of coral spawn during the massive spawning events that occur on the Great Barrier Reef. Most coral reproduce through spawning, releasing sperm and eggs into the water at the same time. The spawn were reared into baby coral inside floating enclosures. The drone, renamed LarvalBot, then carried and released the coral larvae onto damaged reefs in order to help restoration.
