Whose research first revealed that coral reefs are built by tiny animals, not plants?

Quick Answer

The animal nature of corals was established by 18th- and 19th-century naturalists and zoologists. They showed that corals are colonies of animals that secrete calcium carbonate skeletons.

The Full Story

Early naturalists eventually proved that corals are animals rather than plants or rocks. This became clear through careful observation of their feeding structures and behavior. Scientists showed that coral polyps are tiny animals living in colonies, each contributing to the reef-building process by depositing calcium carbonate. That discovery was fundamental to modern marine biology and reef science.

1.Corals were shown to be animals in the 1700s and 1800s
