Alpheus is a genus of snapping shrimp of the family Alpheidae. This genus contains in excess of 250 species, making this the most species-rich genus of shrimp. Like other snapping shrimp, the claws of Alpheus are asymmetrical, with one of the claws enlarged for making a popping noise
This species lives in symbiosis with few goby species. The shrimp, almost blind, digs a large burrow and hosts the goby. In change the fish alerts it of potential predators approaching.
A. djeddensis is associated with the goby genus Amblyeleotris.
