Variable Boring Sponge

Aka coralliphaga


A boring sponge which grows in a wide variety of patterns: they appear as an encrusting sponge; as vase-like tubes extending from coral heads; as finger-like branches extending from the coral; or as tiny tubes extending from dead coral areas. Sulfur- to lemon-yellow, occasionally white.


Inhabit coral reefs and drop-off walls. Bore into corals by secreting minute amounts of acid. This sponge bores large, fist-sized holes in coral heads. From Florida all the Caribbean sea to north Brazil.
