Seastar of the Japanese Wrecks

Shaab Abu Nuhas, or Shaʽb Abu Nuħas, is a triangular-shaped coral reef northwest of Shadwan Island in the northern Red Sea off Hurghada.

The reef is a navigation hazard because it projects into the shipping channel, as evidenced by seven shipwrecks. This includes the SS Carnatic, Kimon M, Olden, Chrisoula K and Giannis D. The reef and the wrecks are popular for scuba diving; four of the wrecks are at a depth of more than 30 metres. The name of the reef is Arabic for "reef of father of copper", after the cargo of one of the wrecks.
