In a fascinating underwater encounter captured by @mo.ib1985 on December 10, 2023, in Khor Fakkan, Sharjah, United Arab Emirates, a video reveals the intricate behavior of a bluestreak cleaner wrasse, Labroides dimidiatus. The footage depicts the smaller wrasse boldly entering the mouth of a larger fish, engaging in a mutualistic dental cleaning ritual. As the author explains, the bluestreak cleaner wrasse is part of a group of cleaner wrasses found in coral reefs across the Eastern Africa, Red Sea, and French Polynesia. These cleaner wrasses establish symbiotic relationships with larger fish, feeding on parasites and dead tissue, providing both nutritional benefits for the wrasse and improved health for their larger counterparts.
