- Corals are widespread and healthy along all shores of the Bay, including those of the west, east and north, and around the islands. The only exceptions are those of the southern sill, separating the Bay from the open sea. Corals on this area were heavily impacted by bleaching in 1998.
- The Park outside Dungonab Bay is heavily dominated by well-developed coral reefs fringing both mainland and islands, and by very extensive offshore patch reefs and barrier reefs extending to approximately 30 km from shore. These coral communities are more typical of the northern and central Red Sea than those inside the Bay.
- Bleaching: is a visual symptom when corals are stressed by changes in conditions such as temperature, light, or nutrients. In this condition os stress, the corals expel the symbiotic algae living in their tissues, which turn them completely white.
