Gymnothorax cinerascens
Shape and Size: A marine organism resembling a snake (eel, anguilliform), characterized by an elongate body. It is cylindrical anterior and becomes laterally compressed toward the tail.Fins: The dorsal and anal fins are fused into a continuous single fold that extends along the body and tail. Notably, the organism lacks pectoral and pelvic fins, a key feature of the Moray eel family (Muraenidae).Teeth: The teeth are generally slender, pointed, and smooth (non-serrated).Maximum Length: The recorded length for this specimen is 57 cm (Total Length, TL).Head: Distinguished by pores with dark margins on the head, serving as a distinguishing trait from similar species.Length before the anal opening: 27 cm, out of the total body length (57 cm). Number of pre-anal vertebrae: 57.Coloring: Uniformly dark brown across the entire body, including the head, lower jaw, and the ventral branchial (gill) region. (The uniform coloration of the lower jaw is significant for species differentiation).Maximum Length: The recorded length for this specimen is 57 cm (Total Length, TL).

ecotype
This ecological niche is clearly exemplified by the Al-Gharqana region within the Nabq Protected Area, where freshwater input from flash floods draining adjacent mountains creates a distinct estuarine transition zone. The success of G. cinerascens in such a uniquehabitat underscores its genetic distinctiveness, confirming the complexityof speciation and adaptation within the Red Sea basin.

The Al-Gharqana region, situated on the coast of the Gulf of Aqaba within Egypt's vast Nabq Protected Area (South Sinai),represents a hydrographically unique coastal strip defined by a fusion of mountainous desert and shallow marine environments. Bounded internally by the Sinai Mountains to the west, Al-Gharqana functions as a natural discharge point where seasonal rainwater and flash floods drain directly into the sea.This inflow creates an estuarine-like transition zone (or quasi-estuary), resulting in a crucial salinity gradient that is rare in the high-salinity Red Sea. This environmental meeting point supports specialized, resilient ecosystems, including vital stands of mangrove trees (Avicennia marina), which thrive in the resultant muddy coastal environment. The area's unique aquatic conditions and turbidity foster high local biodiversity, providing a suitable habitat for highly adaptable organisms (such as Gymnothorax cinerascens) and influencing the composition of its coral reefs, making the region of high biological importance.

phenotype
It has slit-like gills on the sides of the head, and its dorsal and anal fins are fused into a single band that runs the length of the body and tail, but it lacks pectoral or pelvic fins. The jaws are uniformly dark.
