GENERAL NOTE: A near-blind snapping-shrimp living with various shrimpgobies which warn the shrimp of danger and in return feed on small invertebrates excavated and exposed by the shrimp. The shrimp spends most of its time using its pincer-arms to carry and push sand from its burrow and burrow-entrance, while the 1-2 shrimps stand guard. The goby warns the shrimp with a movement of its tail which the shrimp touches with its antennae, and in emergency the goby also dives into the burrow. Widespread with a banded goby, but in the Cook Islands is is with the Pale Shrimpgoby (Ctenogobiops feroculus).
