Most oceanic species (78 per cent, or 44 per cent of all fish species), live near the shoreline. These coastal fish live on or above the relatively shallow continental shelf. Only 13 per cent of all fish species live in the open ocean, off the shelf. Of these, 1 per cent are epipelagic, 5 per cent are pelagic, and 7 per cent are deep water. [16]
During these months, dipterans make up about 50 percent of the freshwater drum's diet. [24] In August through November, they tend to eat fish (which are primarily young-of-the-year Gizzard shad). The percentage of fish in their diet at this time ranges from 52 to 94 percent. [24] Other items in the drum's diet are mollusks and crayfish.

The sea is the habitat of over 1,000 invertebrate species and 200 soft and hard corals and is the world's most northern tropical sea. The Red Sea is a rich and diverse ecosystem.
