Muraena clepsydra

Muraena clepsydra, commonly known as the hourglass moray, is a moray eel found in coral reefs from the Gulf of California to Peru, and the Galapagos Islands. It was described by Charles Henry Gilbert in 1898. It dwells at a depth range of 0 to 25 m. Males can reach a maximum total length of 120 cm, but more commonly reach a TL of 60 cm.

Due to its wide distribution, lack of known threats, and lack of observed population decline, the IUCN redlist currently lists M. clepsydra as Least Concern.
