# Geometric Moray (*Gymnothorax griseus*)

**Taxon:** Moray eel (*Muraenidae*)  
**Conservation Status:** LC - Least Concern  


The Geometric Moray, scientifically known as Gymnothorax griseus, is a type of moray eel found in the western Indian Ocean, including the Red Sea. This interesting creature typically resides in tropical marine environments, often seen in shallow coastal waters, coral reefs, and rocky areas at depths ranging from 1 to 40 meters (3 to 131 feet).

In terms of size, the Geometric Moray can grow up to 65 centimeters (about 25 inches) in length. Its body features a striking visual pattern: it is generally lilac-colored with brown marbling, while its head is brownish adorned with distinct lines of black dots. This unique coloration gives the eel its name. 

The species exhibits simultaneous hermaphroditism, meaning it possesses both male and female reproductive organs at the same time, a trait that is quite rare and has been confirmed using reliable diagnostic criteria. Furthermore, it occasionally becomes host to a parasitic isopod known as Ichthyoxenus puhi.

While the Geometric Moray does hold some interest for minor commercial fisheries, it is not a major target due to its specific habitat and characteristics. The genus name Gymnothorax is derived from Greek, where "gymnos" means naked and "thorax" refers to the breast area.
