Coral: The Primary Architect No discussion of keystone species in this ecosystem can begin without addressing the coral itself. In the Great Barrier Reef, this definition expands to include architects and engineers of the environment.
Defining the Keystone: What Makes a Species Critical? The concept of a keystone species was first coined to describe a predator that maintains the structure of an ecological community. This intricate architecture provides shelter, breeding grounds, and hunting platforms for approximately twenty-five percent of all marine species, making the coral the foundational keystone.
