Orange Spotted Filefish

The orange spotted filefish (Harlequin filefish), scientifically known as Oxymonacanthus longirostris, is a member of the Monacanthidae family and can be found in the tropical waters of the Indo-Pacific region, including the 🌊 Red Sea, the 🇲🇻 Maldives, 🇮🇩 Indonesia, the 🇵🇭 Philippines, and 🇦🇺 Australia. It is important to note that the orange spotted filefish should not be confused with the different species referred to as Cantherhines pullus.

As its name implies, the orange-spotted filefish displays a unique coloration. Its body is primarily white or pale yellow, adorned with striking orange spots that are dispersed throughout its body and fins. The body shape is elongated and laterally compressed, which is characteristic of filefish species. On average, adult orange-spotted filefish measure between 12 and 18 cm (5 to 7 inches) in length.

In their natural habitat, these filefish primarily feed on Acropora polyps, exhibiting a specialized diet.

An intriguing characteristic of the orange spotted filefish is its ability to absorb and utilize chemicals from the Acropora coral it consumes. This behavior enables the filefish to adopt the scent of the coral, providing them with a disguise that helps them evade natural predators such as cod. This unique adaptation sets them apart from other vertebrates. Furthermore, the orange spotted filefish also employs visual camouflage as an additional means of protection.

Overall, the orange spotted filefish is a fascinating species with its distinctive appearance, specific dietary preferences, and remarkable adaptation strategies.
