You can usually find the blue-spotted stingray in the shallow, sandy, or rocky areas on a reef, but unlike its other stingray cousins, it doesn’t bury itself in the sand. It is important for it to stay clean so everyone can see its bright blue spots. These spots are a warning to everyone to stay away because it is venomous.

Like cars, the blue-spotted stingray needs regular cleaning sessions, so it visits cleaning stations on the reef. These are places where small fish and shrimp come to pick bacteria and dead skin off its body. At the cleaning station, everyone wins: the stingray stays clean and the fish and shrimp get to eat the grime off its body. Scientists call this a mutualistic relationship.
