Geometric moray

Distribution : Red Sea and western Indian Ocean.

One spotted head appears at the edge of a reef cavity; another emerges nearby. Juvenile geometric morays have been documented sharing the same refuge, their bodies concealed among the rocks. Only their black-spotted snouts give them away. It would be tempting to see this as organised group life, but sharing a shelter does not establish such relationships.

Good to know

Observe without touching or feeding animals and keep clear of the reef.

WHAT DOES IT LOOK LIKE?

The geometric moray (“Gymnothorax griseus”) has rows of black dots across its brownish-grey head. Its pale grey to lilac body shows faint mottling. It lacks pectoral fins, the side fins found behind the head of many fishes. The dorsal, tail and anal fins form a continuous fringe. It can reach 65 cm.

WHERE DOES IT LIVE?

The geometric moray inhabits coral and rocky reefs in the Red Sea and western Indian Ocean, including the Maldives. It shelters in crevices, from shallow water to depths of about 40 metres.

WHAT DOES IT EAT?

The geometric moray feeds mainly on crustaceans but also catches fish. It often emerges from shelter after dark, holding prey with its teeth before swallowing it.
