Brown Mesh Sea Star

Nardoa galatheae

Nardoa galatheae, or the brown mesh sea star, is a species characterized by its distinctive mesh-like appearance. It typically grows to an average size of 25 centimetres (9.8 inches). This sea star can be found in the Indo-Pacific region, primarily inhabiting coral reefs and rocky substrates at depths of less than 30 meters. Its habitat preference includes areas rich in coral communities, where it can often be spotted resting on the substrate or among the corals. Feeding mainly on detritus and small invertebrates, the brown mesh sea star plays a role in the ecosystem by helping to recycle nutrients. It is likely to feed on turf algae and bacterial films that develop over hard substrates. The species exhibits both asexual and sexual reproduction, with embryos hatching into planktonic larvae before metamorphosing into juvenile sea stars with stubby arms. When encountered while diving, divers may observe the brown mesh sea star clinging to rocky surfaces or coral, blending into its environment. Its unique texture and coloration can make it a captivating subject for underwater photography. Conservation status for this species is currently not evaluated, indicating that there is no specific information regarding its population trends or threats.
