Horastrea indica is a massive colonial coral species that is only found in the Western Indian Ocean on tropical reef systems off the coasts of countries such as Mozambique, Tanzania, Madagascar.
A combination of threats including fish bombing, disease and the impacts of climate change has reduced this species’ habitat. Specific population trends are unkown but widespread declines can be presumed.
The reproductive method of this species is currently unclear. The most common method used by reef building corals is that of broadcast spawning, however the Siderastreidae family contains a diverse group of species that have not been thoroughly studied.
- Order: Scleractinia
- Family: Siderastreidae
- Trend: unknown
- Depth Range (m): 20
This species is only found in the southwest Indian Ocean and along the East African coast and Madagascar.
Habitat and Ecology
This species occurs in shallow, tropical reef environments, generally to depths of 20m, in sandy reef areas.
It is a colonial, stony coral species meaning that as the individual animals (polyps) of this species grow they exude calcium carbonate to form exoskeletons (corallites) for protection.
