A small number of dugongs are also found in the Straits of Johor (which separates Johor in Malaysia and Singapore), in the Philippine provinces of Palawan, Romblon, Guimaras and Davao Oriental, in the Arabian Sea along Pakistan and in the Red Sea in Egypt provinces Marsa Alam. The Dugong reported to be at Marsa Abu Dabbab moved away from there.

  
Was at Marsa Alam early April in the Marsa Shagra Eco-lodge (Red Sea Diving Safari), that's why I know this. You may verify with staff there.
