Cycloseris

Cycloseris is a genus of stony corals, commonly called “plate corals”, belonging to the family Fungiidae. They are solitary, free-living corals that are typically found in shallow tropical waters, often on sandy or rubble bottoms. Plate corals are characterized by their flat, disc-shaped skeletons with radiating, radial ridges. They are important members of coral reef ecosystems and contribute to the biodiversity and ecological balance of these vibrant marine habitats.

Common Names

Cycloseris corals are commonly known as "plate corals" or "mushroom corals" due to their distinctive flat, disc-shaped appearance. This morphology distinguishes them from other coral genera within the Fungiidae family.

Characteristics

Cycloseris corals exhibit several key characteristics that distinguish them from other corals:

  • Solitary: They are solitary corals, meaning they do not form colonies like many other coral species.
  • Free-living: Unlike many other corals that attach to hard substrates, plate corals are free-living, meaning they can move around on the seafloor.
  • Flat, disc-shaped skeleton: The most distinctive feature of Cycloseris is their flat, disc-shaped skeleton, which gives them a plate-like or mushroom-like appearance.
  • Radial ridges: The skeleton of Cycloseris exhibits radiating, radial ridges that contribute to its unique appearance.
  • Oral disc: The oral disc, where the mouth is located, is typically located in the center of the upper surface of the coral.

Environment

Cycloseris corals are commonly found in shallow tropical waters, typically in depths of 1 to 30 meters. They prefer sandy or rubble bottoms, as they are free-living and need a substrate that allows for movement. They are often found in areas with strong currents, which help to provide them with food and oxygen. Cycloseris corals play an important role in coral reef ecosystems, providing habitat for other marine organisms and contributing to the overall biodiversity of the reef.
