Homophyllia bowerbanki is a vulnerable species of coral found in the Pacific and Indian Oceans.

This species is moderately common, but it is threatened by crown-of-thorns starfish predation and habitat loss.

Homophyllia bowerbanki is a small, encrusting coral but occasionally reach a diameter of over 1.5 metres (4.9 ft).

[2] It obtains most of its nutritional needs from the symbiotic dinoflagellates that live inside its soft tissues.

The main threats faced by corals in general are related to climate change and the mechanical destruction of their coral reef habitats; increasing damage from extreme weather events, rising sea water temperatures and ocean acidification.
