The Red Sea Longnose Filefish, scientifically known as Oxymonacanthus halli, is a small, striking fish found in the coral reefs of the Red Sea.

Description & Characteristics

The Red Sea Longnose Filefish is a small species, reaching a maximum size of 7.0 cm. They are easily recognized by their elongated snout, which gives them their common name. Their body is typically a pale yellow to white color, adorned with scattered dark brown spots. This color pattern helps them blend seamlessly into the coral reef environment. They have a single, sharp dorsal spine that is positioned at the front of their dorsal fin. The caudal fin is slightly rounded, and the pelvic fins are reduced to small spines.

Habitat and Occurrence

The Red Sea Longnose Filefish, Oxymonacanthus halli, is a common inhabitant of coral reefs in the Red Sea. It is found in a range of depths, typically inhabiting shallow reefs and lagoons. They are particularly fond of areas with abundant coral growth, as this provides both shelter and a source of food.

Taxonomy

The Red Sea Longnose Filefish, Oxymonacanthus halli, is a member of the Family Monacanthidae, which is a family of fishes commonly known as filefishes. They are classified within the Order Tetraodontiformes, a group that includes pufferfishes, triggerfishes, and ocean sunfishes. This order falls under the Class Teleostei, which represents the majority of bony fishes.

Feeding

The Red Sea Longnose Filefish is a specialist feeder, primarily consuming coral polyps. Their diet consists almost exclusively of these tiny, invertebrate organisms, making them a “corallivorous” species. They use their sharp teeth to scrape polyps off the coral surfaces, demonstrating a unique adaptation for feeding on this specific food source.
