The image depicts a marine scene with a large, dark-colored fish swimming near a coral reef. The fish appears to be a type of marine mammal, possibly a whale or dolphin, and is surrounded by various types of marine vegetation, including sea grasses and other aquatic plants. The background features a deep blue ocean with some light reflections, suggesting it might be taken during the daytime. There is also a text overlay in the bottom right corner of the image, which seems to be in Vietnamese, indicating that this image might have been taken in Vietnam.
