Gymnothorax longinaris, also known as the Longfin Moray, is a species of moray eel found in the Indo-Pacific region. This eel is characterized by its slender body and long dorsal fin, which extends almost to the tip of its tail.

Description & Characteristics

Gymnothorax longinaris is a relatively small moray eel, reaching a maximum size of 23.7 cm. The body is elongated and cylindrical, with a pointed head and a small mouth. The eyes are small and black. The dorsal fin extends almost the entire length of the back, merging with the anal fin and forming a continuous fin that wraps around the tail. The body is covered in small, overlapping scales, and the coloration is typically a mottled brown or gray, with darker blotches and spots. The Longfin Moray has a distinctive feature, a single, prominent dark spot located just above the pectoral fin, which helps distinguish it from other species.

Habitat and Occurrence

Gymnothorax longinaris is a benthic species, meaning it lives on or near the bottom of the ocean. It is typically found in shallow, rocky reefs and seagrass meadows. Its distribution encompasses the Indo-Pacific region, ranging from the Red Sea and the eastern coast of Africa to the Pacific islands. The Longfin Moray is particularly prevalent in the tropical and subtropical marine zones, specifically within the neritic zone, the region of the ocean that extends from the shoreline to the edge of the continental shelf.

Taxonomy

Gymnothorax longinaris belongs to the Class: Teleostei, the most diverse class of bony fishes, and the Order: Anguilliformes, which encompasses eels. This species is further classified within the Family: Muraenidae, known for its diverse range of moray eels. Gymnothorax longinaris is a representative of the diverse and intriguing world of moray eels, showcasing the adaptability and diversity of life in the marine realm.

Feeding

Gymnothorax longinaris is a carnivorous predator that feeds on a variety of small marine animals, including crustaceans, fish, and cephalopods. Its strong jaws and sharp teeth enable it to effectively seize and subdue prey. Like many moray eels, Gymnothorax longinaris typically ambushes prey from hiding places within the reef. The longfin moray’s diet consists largely of small fish and invertebrates.
