@ourunderwateruniverse: The vibrant reality of a healthy coral reef ecosystem. 🪸 If you watch closely, a graceful pair of Threadfin Butterflyfish swims right into the frame. Fun fact: The populations of this specific species that live in the Red Sea completely lack the false "eyespot" on their back fin that their cousins in the Pacific Ocean have! It is one of the many unique evolutionary details of this incredible underwater ecosystem. Save this video for your daily nature escape, and let me know your favorite ocean creature in the comments. #redseadiving #marinelife #scubadivingtok #butterflyfish
