This is a very close capture of a parrotfish head that shows the beauty of the details: this fish has a distinctive mouth and in the picture's background, we see a rocky coral reef.
This shot was captured in Naama Bay, Sharm El Sheikh, in the Red Sea Governorate, Egypt. It is in relation to SDG 14: Life Below Water, which states: "Conserve and sustainably use the oceans, seas and marine resources for sustainable development".
