Tetralia crabs actively clean sediment off their host corals, enabling small corals to survive in high-sediment areas where they would otherwise be smothered.
|Crabs of the genus Tetralia are found throughout the Indo-Pacific. T. nigrilineata has been reported from the Great Barrier Reef in Australia, the Cook Islands, and New Caledonia.|
|Shallow tropical reefs, reef flats and lagoons where Acropora corals grow.|
|Tetralia live only on Acropora corals and feed on their mucus.|
