Imagine gliding along a vibrant coral reef in the Caribbean or Eastern Pacific, and spotting a unique, brain-like structure clinging to the seabed. That's likely Lobed Star Coral (Orbicella annularis), a reef-building coral that adds character to the underwater landscape. While its exact size is unknown, it forms impressive colonies with distinctive lobed or columnar shapes. Divers and snorkellers might find it from the surface down to considerable depths, although it's more common in shallower, sunlit areas. This coral plays a crucial role in building and maintaining the reef ecosystem, providing habitat and shelter for countless marine creatures. Although it may not be the flashiest resident of the reef, its architectural contributions are undeniable.
Lobed Star Coral is easily recognised by its distinctive lobed or columnar growth form, resembling a brain or a series of fused fingers. Its surface is covered in small, star-shaped patterns, giving it a textured appearance. While colour can vary, it's often a shade of brown or yellowish-brown. This coral is typically found attached to hard substrates on the reef, and its sturdy structure distinguishes it from softer corals.
