What is a bright color spot on the background of a coral reef? It stands out even against the background of the corals. Most likely it is the nudibranch.
For macrophotography and colourfulphotograph contest.
One of the most favorite objects for shooting. And the nudibranch can be photographed from the front and back. In one case, the frame will have its horns. In another - a small colored bush. This is his gills. In case of danger, the molyusuke hides its gills inside. That they again appeared, you need to wait a little.
