Biology     Glossary (e.g. epibenthic)

Minimum depth from Ref. 81548. Cryptic on coral areas and reef patches (Ref. 78188). On a reef slope (Ref. 97449). Feeds on hard corals, soft corals, encrusting organisms, algae, gorgonians and cannibalistic on other Acanthaster planci (Ref. 78188). Life cycle: Eggs hatch into planktonic larvae, grow into algal and coral feeding juveniles, and later into fully grown adults (Ref. 83567). Also Ref. 113703. Spawning period in the Southern Hemisphere is from November to January while in the Northern Hemisphere, May to August. Spawning duration is about 30 minutes. Aggregation and synchronization during spawning is triggered by pheromone but is only effective over short distances (Ref. 78188).
