Wire Coral, scientifically known as Cirrhipathes anguina, is a striking and unique species of coral characterized by its slender, whip-like branches. This coral species, belonging to the black coral family, is an essential component of many marine ecosystems, showcasing a remarkable adaptation to its environment.
Description and Characteristics
Cirrhipathes anguina is a colonial organism, meaning it forms a colony of interconnected polyps. Its skeleton is composed of a black, thorny axis, giving it the distinctive wire-like appearance. This axis, known as the “scleraxis,” is the defining feature of the black coral family and is covered in a thin layer of living tissue. The polyps are small and have eight tentacles, which they use to capture food. The maximum size of the colony can vary, with some specimens reaching lengths of several feet.
Habitat and Occurrence
Cirrhipathes anguina is a common inhabitant of the deep-sea, with a depth range extending from 100 meters to over 1,000 meters. It is often found in areas with strong currents, where it attaches itself to rocks, ledges, and other hard substrates. This coral species is particularly prevalent in the mesophotic zone, the twilight zone where sunlight is limited. It can also be found in the bathyal zone, where light is absent.
Taxonomy
Cirrhipathes anguina is classified under the phylum Cnidaria, which encompasses all corals, jellyfish, anemones, and hydroids. This species belongs to the Class: Hexacorallia, Order: Antipatharia, and Family: Antipathidae. The Antipatharia order is commonly referred to as the black corals, characterized by their black skeletons and unique morphology.
Feeding
Like other corals, Cirrhipathes anguina is a suspension feeder, primarily consuming plankton. The polyps extend their tentacles, capturing small organisms and detritus carried by the currents. The feeding habits of Cirrhipathes anguina are adapted to the low-light conditions of the deep-sea, where food sources are less abundant.
