Characteristics
Plexauridae corals are colonial animals, meaning they are composed of many individual polyps that are connected to one another. The polyps are small, typically less than 1 cm in diameter, and they are arranged in a branching pattern. The branches are usually flexible and can sway in the current. Plexauridae corals have a unique skeletal structure made up of a network of spicules, which are microscopic, needle-like structures made of calcium carbonate. These spicules provide support and rigidity to the colony, but they also give it its characteristic rough texture.
Environments
Plexauridae corals are found in a wide variety of marine environments, but they are most commonly found in shallow, tropical and subtropical waters. They prefer clear, well-lit waters with strong currents. Plexauridae corals can be found attached to rocks, coral reefs, and other hard substrates. They are often found in areas where there is a lot of wave action, as this helps to keep their branches clear of sediment and debris.
Common Names
Plexauridae corals are commonly known as:
- Sea whips
