During the night, a deep sea community of marine life that spends daylight hours at depths of up to hundreds of meters, now begins to migrate upward and towards the shore. As these riches come within reach, spinner dolphins begin to hunt. Small subgroups spread out across the sea. Using echolocation, the spinners scan the darkness. and using their whistles, they call members of the school back together to unite in defense. The collective defenses of the dolphin school protect each member from harm. Dolphins and whale attract every year tourists to Egypt, but, despite their popularity, are still poorly known from a scientific point of view. Eight species are considered regular: Common Bottlenose Dolphin (Tursiops truncatus), Indopacific Bottlenose dolphin (Tursiops aduncus), Spinner Dolphin (Stenella longirostris), Pantropical Spotted Dolphin (Stenella attenuata), Longbeaked Common Dolphin (Dephinus capensis), Risso’s Dolphin (Grampus griseus), Humpback Dolphin (Sousa chinensis) and Bryde’s Whale (Balaenoptera edeni). Other height species are considered rare (Notarbartolo et.al. 2007).
