Zebra Moray

The Zebra Moray (Gymnomuraena zebra) is a distinctively patterned moray eel and the only member of its genus, found across the Indo-Pacific from the Red Sea and East Africa to the eastern Pacific coast of the Americas. It inhabits coral reefs and rocky shorelines, where it uses blunt, peg-like teeth to crush the shells of crabs, mollusks, and sea urchins rather than gripping fish prey. Its bold pattern of narrow pale bands against a dark body gives it its common name and makes it one of the more visually recognizable morays on Indo-Pacific reefs. It is generally shy and reclusive, spending most of daylight hours hidden within reef crevices, and is not considered threatened.

Zebra Morays have a thick, cylindrical body typical of morays, without pectoral or pelvic fins, and a continuous fin margin running along the back, tail, and underside.

Key field marks:

• Dark brown to blackish body crossed by numerous narrow, creamy-white to pale yellow vertical bands, resembling zebra stripes
• Blunt, rounded snout with small eyes
• Flattened, peg-like teeth adapted for crushing hard-shelled prey, distinct from the sharp fangs of fish-eating morays
• Robust, muscular build relative to its length

Adults typically reach 60-150 cm. Its continuous fine banding readily separates it from the blotchy, irregular spotting of the similarly colored snowflake moray, and it is the only moray species with this particular striped pattern across most of its range.

Zebra Morays are found throughout the tropical Indo-Pacific, from the Red Sea and East African coast across Southeast Asia and Australia to Hawaii and the Pacific coast of Central America. They typically inhabit coral reefs and rocky reef habitats at depths from close to shore down to around 40 m, favoring crevices, caves, and holes among coral or rock where they shelter during the day. This species prefers areas with an abundance of hard-shelled invertebrate prey such as crabs and sea urchins, often near reef flats or rubble zones. It is generally solitary and maintains a fixed home crevice that it returns to repeatedly.

Zebra Morays are mostly nocturnal, remaining hidden within a reef crevice during the day and emerging after dark to forage over the reef and surrounding rubble. Using strong jaws and blunt, molar-like teeth, they specialize in crushing the shells of crabs, mollusks, and sea urchins rather than pursuing fast-moving fish prey. They are generally solitary and can be territorial toward other eels near a preferred den, though they are considered relatively docile and less likely to bite defensively than more aggressive moray species. As with other morays, reproduction involves broadcast spawning followed by an extended pelagic leptocephalus larval stage before juveniles settle onto reef habitat.
