The giant moray is one of the two largest species of morays. It reaches 3 meters in length and weighs up to 30 kg, and its lifespan is approximately 36 years.
Juveniles have brown-yellow coloration with many large black spots. In adult giant morays, the camouflage coloration resembles leopard patterns. The head, upper part of the body, and fins are colored in yellow-brown tones with various large black spots. The ventral side lacks a pattern.
The moray's body is compressed laterally and covered with a layer of mucus, providing safe sliding and penetration into shelters, as well as protection from mechanical damage and parasites.

The dorsal fin extends along the entire body, providing the moray with high speed without loss of maneuverability.
The huge mouth of the Giant Moray is full of sharp fang-like teeth, located on two pairs of jaws – the second pair is deep in the throat but can protrude to capture prey and move it to the esophagus.
This species of moray is distributed in the tropical zone of the Indo-Pacific region. It inhabits clear lagoons and reef slopes facing the open sea. Often found along deep drop-offs and slopes, preferring a bottom-dwelling lifestyle. Juveniles hide in the tidal zone of flat coral reefs.
Giant morays occupy the top of the food pyramid, and it is believed that they have no natural enemies. On the contrary, adult morays often attack reef sharks. But usually the diet includes mainly fish, sometimes crustaceans.
