Turbinaria cf. peltata
This reef-building coral forms colonies of flat, often undulating, overlapping plates, but sometimes vertical columns also occur. A single colony of numerous individual polyps can grow up to several meters in diameter. When the large, greyish-brown polyps are extended, as they frequently are during daytime, the surfaces of the colony have a furry, carpet-like appearance. Unlike other Turbinaria species, T. peltata is zooxanthellate. This means that this species occurs in shallower waters in order for the hosted single-celled organisms to perform photosynthesis. The coral benefits from the energy produced by this process.
Distributed widely in shallow waters of the Indian Ocean and the western Pacific.
Not very common in the Davao Gulf, based on my personal experience. Perhaps this species isn't as aggressive as other stony coral varieties here. Spotted this colony at a depth of 7m at the Coral Gardens dive site, off the northeastern coast of Talikud Island.
