Abstract

The corallivorous Crown of Thorns starfish, Acanthaster planci, has contributed greatly to the decline of coral coverage in reefs throughout the Indo-Pacific region (reviewed in Pratchett et al. 2014). To date, little information is available on the reproductive timing and controlling factors for A. planci, particularly in the Northern Hemisphere (Bos et al. 2013). More detailed information on the timing and controlling mechanisms for this species is necessary to understand its population dynamics and dispersal patterns.

In mid-September of 2014, spawning by A. planci was observed on the island of Koh Tao, Gulf of Thailand, providing the first record of natural spawning for this species in the proximity of the South China Sea.
