Pseudodiploria clivosa, the knobby brain coral (family Mussidae), is a massive scleractinian coral endemic to the Caribbean Sea, forming brain-coral-like hemispherical colonies with meandering ridges and valleys on shallow reef crests and slopes. It is closely related to P. The species is a significant reef-builder in the Caribbean and is affected by coral bleaching and stony coral tissue loss disease (SCTLD). Genomic data have been generated for this species and are available in public databases, enabling comparative studies of cnidarian evolution and ecology.
