Shrimp Cleans Grouper's Jaws

Occurred on June 21, 2023 / Ishigakijima, Okinawa, Japan

Info from Licensor: "A large Tomato Grouper with its mouth wide open. A Scarlet Skunk Cleaner Shrimp is flying around near it. It is a Cleaner Shrimp, and it is cleaning the Tomato Grouper. Neither Tomato Grouper nor Cleaner Shrimp was taught by anyone. But Azahata won't eat him, and Cleaner Shrimp isn't afraid of him either. It is amazing how nature works."
