Definition of Reef:
Reefs are hard mineral substrates such as rocks, till, or stones, primarily moraine ridges with block and stone cover in gravel/sandy surroundings, which rise mildly to prominently above the seafloor;[1].
  • biogenic hard substrates such as honeycomb (Sabellaria) reefs and mussel banks are present;
  • they are permanently submerged;
  • often they are overgrown with mussels and a characteristic macrofauna.

Reefs can be both natural and artificial[2].

Reefs have a number of ecological functions:[3]

  • feeding grounds for birds and marine mammals;
  • habitat and retreat;
  • habitat and nursery area with high species diversity;
  • spawning grounds and feeding ground for fish;
  • stepping-stone and regeneration reservoir for the expansion of benthic organisms.
This is the common definition for Reef, other definitions can be discussed in the article
