You may be looking at this and thinking, “What a cool underwater plant,” but in reality, the black sea whip is actually part of the black coral group. However, in the wild, they aren’t always black to the naked eye—just their internal skeleton is. You can find these wispy corals in marine environments, particularly in the Caribbean Sea and western Atlantic Ocean. Despite the name "black coral," they're more closely related to sea anemones and jellyfish than to hard corals. So really, they’re a contradiction in both appearance and classification in a lot of ways. Either way, they make for an excellent piece to add to your aquatic collection of curios.
