Oriental Batfish

Platax orbicularis

The oriental batfish (Platax orbicularis), also known as the orbicular batfish, is a large, laterally compressed fish reaching up to 50 cm in length. Adults have a nearly circular body profile with a silvery to dusky grey coloration and a dark band through the eye. Juveniles are dramatically different, with extremely elongated dorsal and anal fins and an orange-brown coloration that mimics fallen leaves floating on the surface, providing camouflage from predators. As they grow, the fins become proportionally shorter and the body more rounded. Batfish are found throughout the Indo-Pacific on coral reefs, lagoons, and around wrecks and artificial structures. They are among the most diver-friendly fish on the reef, frequently approaching divers with apparent curiosity, circling them closely and following for extended periods. They often form small schools of 5-20 individuals that hang in mid-water near drop-offs, wrecks, and cleaning stations. Batfish feed on algae, invertebrates, and jellyfish, and play an important role in reef recovery by consuming seaweed that can overgrow damaged corals.
