Amblyeleotris (Say it: AMM-BLEE-lee-oh-TRISS) is a genus of fish in the family Gobiidae found throughout the Indo-Pacific region. This is the largest genus of the shrimp gobies or prawn gobies, so-called because of their symbiotic relationship with certain alpheid shrimps. The shrimp excavates and maintains a burrow used by both animals while the goby, which has far superior eyesight, acts as a lookout for predators. The shrimp maintains almost constant contact with the fish with an antenna. These species vary considerably in size from less than 30 mm to almost 200 mm standard length.
