A very beautiful calcified algae that is spherical in shape, resembling a pinecone. Native to the reef flat, it grows in sandy substrate among sea grass beds and Halimeda forests. There are several distinct species including Brevifolius and Longifolius that are similar in shape and characteristics. Its root-like structure is a large bulb with a series of rhizoids that anchor it to substrate, and sometimes rocks. Mature plants reach a height of about 6" and 2-3" in diameter. Like most calcareous stem plants, it needs a deep sand bed of 4" or more to grow in the aquarium. Calcium supplementation is needed. Not palatable to fish or invertebrates.
