Behaviour
S. hystrix is a common and geographically widespread species that is common in shallow reef environments.
The reproductive strategy of this species reflects its opportunistic ecology. S. hystrix is a broadcast spawning hermaphroditic brooder, with the male gametes mobile. The fertilised embryo develops in situ, hence the term brooding corals. Like P. damicornis, it does have the ability to produce asexual planulae as well. Most planulae settle within 100m of the parent colony, however in several populations, the genetic signtaures of more distantly derived larvae were also detected.
