Red Sea Moses Sole

Pardachirus marmoratus

The Red Sea Moses Sole, Pardachirus marmoratus, is a flatfish residing in the western Indian Ocean, extending from the Red Sea to Sri Lanka and along the east African coast to Durban. This species is typically found in shallow coastal waters, preferring depths between 1 and 15 meters. It thrives on sandy or muddy seabeds, often near coral reefs, where its coloration helps it blend into its surroundings. As juveniles, these fish are symmetrical, but as they grow, their left eye shifts to the right side, resulting in a flattened body. Their color ranges from whitish to pale brown or grey, with distinctive dark brown rings and spots that provide effective camouflage. Feeding mainly on invertebrates that live on the ocean floor, the Red Sea Moses Sole is well-suited to its bottom-dwelling lifestyle. Divers might spot this fish resting on the seafloor, often partially buried with only its eyes and nostrils visible. Notably, this species can secrete a milky toxin from its dorsal and cloacal fins, which acts as a deterrent to predators, including sharks. The toxin, known as pardaxin, has been studied for its potential use in shark repellents and other biotechnological applications. The Red Sea Moses Sole is categorized as Least Concern by the IUCN, and it is caught for commercial purposes and sold fresh, despite its toxic defense mechanism. Divers should exercise caution and avoid disturbing the fish to prevent any irritation from its toxin.
