The tiger shark was spotted on Friday and has reportedly been subjected to several investigations by marine experts.

There were no casualties. The survivors, some of whom are British, plan to sue the owners for operating a ship that was not fit to sail.

Egypt's Red Sea resorts are among the world's most popular diving destinations, and provide significant part of Egypt's 12 percent of GDP coming from tourism.
