Isididae
Isididae is a family of colonial corals that are commonly known as “wire corals” or “lace corals.” These unique organisms are found in a variety of marine environments, primarily in tropical and subtropical waters. Isididae belong to the order Alcyonacea, which includes soft corals and sea fans.
Characteristics
Isididae are distinguished by their delicate, branched skeletons that are composed of a material called gorgonin. Gorgonin is a protein that is similar to keratin, which is found in human hair and nails. The skeletons of isidids are often very fragile and can be easily broken. Their polyps are small and usually have eight tentacles, a characteristic of octocorals. The polyps are scattered along the branches of the skeleton and are responsible for feeding and reproduction.
Environments
Isididae are typically found in shallow, clear waters where they can attach themselves to rocks, coral reefs, and other solid substrates. Some species are also found in deeper waters. They thrive in environments with moderate water flow and good light penetration.
Common Names
Isididae are commonly known as "wire corals" or "lace corals" due to their delicate, branched skeletons. Other names used to describe members of this family include "bamboo corals" and "feather corals."
