Amblyeleotris randalli, commonly known as Randall’s prawn goby, is a species of small marine fish belonging to the family Gobiidae. Here are some key characteristics and facts about Amblyeleotris randalli:

1. Appearance: Randall’s prawn goby has a slender body with a pointed snout. It typically has a white to cream-colored body with distinctive dark brown to blackish markings, which can vary in pattern and intensity. These markings often include stripes or spots along the body and fins.
2. Size: They usually grow to a size of about 7-9 centimeters (2.8-3.5 inches) in length.
3. Habitat: This species is found in the tropical waters of the western Pacific Ocean, particularly in areas with sandy or silty substrates near coral reefs or rubble zones. They are commonly associated with burrows or holes in the substrate.
4. Behavior: Randall’s prawn gobies are symbiotic with pistol shrimp (genus Alpheus). They form a mutualistic relationship where the goby maintains contact with the burrow and acts as a lookout for predators, while the shrimp excavates and maintains the burrow. They feed on small invertebrates and zooplankton.
