Abu Galawa Soraya, Hamata (2009).
The pic was made from far so it was mostly blueish. I have changed it to B&W for better contrast.
This is one of the biggest moray eels, reaching up to 3 m in length. Its body has a brownish background color. While juveniles are tan in color with large black spots, adults have black specks that grade into leopard-like spots behind the head and a black area surrounding the gill opening. It is widespread in many tropical seas, including the Red Sea.
