• Mesophotic ecosystems (MEs) are characterized by the presence of light-dependent organisms, found at depths ranging from ~30 to 150 m in temperate, subtropical and tropical regions.

• Mesophotic communities occasionally create massive reef structures with diverse but characteristic morphologies, which serve as the framework builders of those ecosystems.

• MEs are physically linked with shallow and deep-sea habitats, and while taxa from both environments share this space, unique and endemic biodiversity is also found.
