Coral reefs are primarily composed of calcium carbonate, which is secreted by coral polyps, leading to a solid structure. However, the reefs themselves can have hollow spaces within them, created by the living organisms and the complex ecosystem that inhabits them. These hollow areas provide habitats for various marine species, contributing to the biodiversity of the reef. Overall, while the structural framework of coral reefs is solid, it contains many interconnected voids.
