Lobsters' corals are a type of coral found in the shallow waters of the Caribbean Sea. They are characterized by their bright red and orange colors, and are often found in large colonies. ROES stands for Red Orange Encrusting Sponges, which are a type of sponge that often grows on the surface of the Lobsters' corals. These sponges provide additional protection for the coral, as well as providing food for the lobsters that inhabit the area.
