Cirrhipathes
Cirrhipathes is a genus of black corals found in tropical and subtropical waters around the world. They are colonial organisms, meaning they are made up of many individual polyps that live together as a single organism. Black corals are known for their intricate branching structures and their dark, often black, skeletons.
Common Names
Cirrhipathes corals are commonly referred to as "black corals," "wire corals," or "sea whips."
Characteristics
Cirrhipathes species have several distinctive characteristics that help to distinguish them from other corals:
- Skeletal Structure: Their skeletons are made of a tough, flexible material called gorgonin, which gives them a whip-like appearance. The skeleton is usually black or dark brown, but can sometimes be reddish or yellowish.
- Polyp Morphology: The polyps are small and have eight tentacles, which are used to capture food. They are arranged in rows along the branches of the coral colony.
- Growth Habit: Cirrhipathes corals typically grow in a branching or whip-like form, often forming dense thickets. They can reach sizes of several meters in length.
Environments
Cirrhipathes species are found in a variety of marine environments, including:
- Coral reefs: Black corals are often found in the deeper, darker parts of coral reefs, where light levels are low.
- Sea Mounts: These corals can also be found on seamounts and other underwater structures.
- Rocky Substrates: Some species prefer rocky substrates where they can attach themselves.
