Galaxea Branching Coral

Galaxea horrescens


The colonies of this species of stony coral is arborescent (look like trees due to branching). Its tubular corallites are thin-walled with flaring rims. Its tapering, translucent tentacles are usually extended only at night. It propagates by fragmentation.


This species is found in the central Indo-Pacific, northern, western, and eastern Australia, West Philippine Sea, and the oceanic West Pacific. Usually found in reef areas with good water circulation and light availability, up to depths of 25m.


Spotted this odd-looking hard coral at a depth of about 20m, off the western coast of Samal Island, Philippines.
