โฆ Synopsis
The rate of decomposition of 67 crown-ofthorns starfish was monitored over 7-9 days on 2 reefs of the Great Barrier Reef in 7 permanent quadrats in different depths and habitats. The pattern of decomposition was similar in all quadrats irrespective of the site or depth. Many different organisms, including crown-ofthorns starfish, fed on or scavenged the remains. Despite this activity the remains could be recognised as crown-ofthorns starfish for up to 5 days. The reason for the sudden disappearance of starfish at the ends of outbreaks is briefly discussed.
