Reefs Unleashed

This plate from an autonomous reef monitoring structure (ARMS) was put on a reef in Bali for a year. Over that time the plate was covered by different kinds of animals. When scientists retrieve these units after a year, one of their first tasks is to try to identify the animals that have moved onto the plates. Do you want to give it a try? Click Next; then use the reference key to identify three different animals that you see highlighted in subsequent steps. Good luck!
