Leptoseris

Leptoseris is a genus of stony corals in the family Agariciidae. It is commonly known as the “thin-plate coral” due to its distinctive flattened and delicate appearance. Leptoseris corals are characterized by their thin, plate-like skeletons that branch and often form intricate patterns. These corals are found in a variety of tropical and subtropical reef environments, where they play an important role in the ecosystem.

Common Names

Leptoseris corals are commonly known as "thin-plate corals". They are also sometimes referred to as "leaf corals" or "finger corals", depending on their specific morphology.

Characteristics

Leptoseris corals exhibit several distinct characteristics:

  • Thin, Plate-Like Skeleton: Leptoseris corals have thin, flattened skeletons that are easily distinguished from the thick, massive skeletons of other coral genera. These skeletons often have a delicate, lace-like appearance.
  • Branching and Fusion: Leptoseris colonies typically branch and fuse together, creating intricate patterns. These patterns can vary greatly depending on the species and environmental conditions.
  • Small Corallites: The individual corallites (the skeletal cups that house the polyps) are small and numerous. They are often arranged in a regular, radial pattern.
  • Coloration: Leptoseris corals exhibit a range of colors, including brown, green, yellow, and orange. Their coloration can be influenced by factors such as light availability and the presence of symbiotic algae.

Environments

Leptoseris corals are found in various tropical and subtropical reef environments. They are particularly common in:

  • Shallow Reef Flats: Leptoseris often grows in shallow, sunlit areas on reef flats, where they have access to ample sunlight for photosynthesis.
  • Reef Slopes: These corals can also be found on the slopes of reefs, where they may occur in deeper water.
  • Lagoons: Leptoseris is sometimes found in lagoons, particularly in areas with good water circulation.
